ID : in-4-Full-Year-4th-Grade-Review [3] Answers (1) 7043 Step 1 Since we know that there are 1000 grams in 1kg. Step 2 The above given quantity 7kg 43g becomes 7000g + 43g = 7043g. (2) 21 Step 1 Let us count the number of blocks in the given figures: 1st: 1 2nd: 3 3rd: 6 4th: 10 5th: 15 Step 2 If we observe carefully, the number of blocks in every figure is increasing by a count of 2, 3, 4 and so on. Step 3 From 4th to 5th figure the increment in number of blocks is 5, so from 5 th to 6th figure the increment will be 6. This means, the next figure will have 15 + 6 = 21 blocks.

The number of pastries in one set = 24 Step 2 Out of the 24 pastries she made, the number of over-baked pastries =1/4 of the 24 pastries 24 = pastries 4 = 6 pastries Step 3 The number of remaining pastries = 24 - 6 = 18 pastries Step 4 The number of extra sets she made = 4 The number of pastries in these 4 sets = 4 × 24 = 96 pastries Step 5 Total number of pastries = Remaining pastries from first set + Number of pastries in 4 sets = 18 + 96 = 114 pastries Step 6 Therefore, the total number of pastries she has now is 114. (4) 687 Step 1 There are three types of trees in Neha's farm house. Step 2 To find the total number of trees in Neha's farm house, we must add the number of trees of each type. Step 3 This means, the total number of trees in Neha's farm house = Number of banana trees + Number of peaches trees + Number of apple trees. = 313 + 104 + 270 = 687 Step 4 Hence, there are 687 trees in Neha's farm house.

B) sixty-eight lakh eighty-eight thousand six hundred twenty-five Step 1 In the Indian numbering system, we use periods like ones, tens, thousands, lakhs, crores, etc. Step 2 Let us write the number 6888625 in groups according to the Indian system of numbers: 68,88,625 Step 3 Therefore, the number name for the number 68,88,625 is sixty-eight lakh eighty- eight thousand six hundred twenty-five. (6) 119561 (7) 837 Step 1 Total amount earned by the shopkeeper in one year = Rs. 300548 Step 2 Amount spent by the shopkeeper over the year = Rs. 299711 Step 3 Therefore, the total amount left with the shopkeeper at the end of the year = Amount earned - Amount spent = Rs. 300548 - Rs. 299711 = Rs. 837 Copyright 2017 www.edugain.com Personal use only.

Step 2 This means, the total population of the town = The number of men + The number of women + The number of children = 648356 + 894734 + 809803 = 2352893. (9) 1 cm Step 1 Let us first calculate the length of pencil A and pencil B. We can see that the length of pencil A begins at 0 cm and ends at 4 cm. Similarly, the length of pencil B begins at 0 cm and ends at 3 cm. So, Length of pencil A = 4 cm - 0 cm = 4 cm Length of pencil B = 3 cm - 0 cm = 3 cm Step 2 Since, 3 cm < 4 cm, we can conclude that pencil A is longer than pencil B. Step 3 Let us calculate the difference between the lengths of the two pencils: Length of pencil A - Length of pencil B = 4 cm - 3 cm = 1 cm Step 4 Hence, pencil B is 1 cm shorter than pencil A.

ID : in-4-Full-Year-4th-Grade-Review [7] (10) 8 feet Step 1 For being able to measure a length using a rod, the length should be a multiple of the length of the rod. Step 2 So, a length that can be measured using either of the rods must be a multiple of the lengths (common multiple) of both the rods. Step 3 Since we need to find smallest such length, we are looking for the Least Common Multiple (LCM) of the lengths of the two rods. Step 4 The LCM of 8 and 4 is 8 feet. (11) 10000 Step 1 Let us write one crore as a number: 10000000 Step 2 The number that is 1000 times smaller than one crore can be found by dividing 10000000 by 1000: 10000000 = 10000 1000 Step 3 Therefore, 10000 is the number that is 1000 times smaller than one crore. (12) A) 800 Step 1 We know, 1 liter = 100 centiliters. Step 2 Therefore, 8 liters = 100 × 8 = 800 centiliters. Copyright 2017 www.edugain.com Personal use only. Commercial use is strictly prohibited. ID : in-4-Full-Year-4th-Grade-Review [8] B) 7000 Step 1 We know, 1 meter = 1000 millimeters. Step 2 Therefore, 7 meters = 1000 × 7 = 7000 millimeters. C) 14000 Step 1 We know, 1 gram = 1000 milligrams. Step 2 Therefore, 14 grams = 1000 × 14 = 14000 milligrams. D) 8000 Step 1 We know, 1 liter = 1000 milliliters. Step 2 Therefore, 8 liters = 1000 × 8 = 8000 milliliters. (13) 3120871 Step 1 Here, we are looking for a number which is 25041 more than 3095830. Step 2 We can find such a number by adding 25041 to 3095830. Step 3 Let us now add the numbers 25041 and 3095830 as below: 25041 + 3095830 Sum 3120871 Step 4 Thus, 25041 more than 3095830 is 3120871.

ID : in-4-Full-Year-4th-Grade-Review [9] (14) > Step 1 To obtain the greater of the two numbers, we will use the following steps: A. First, we compare the number of digits. The number with more digits will be greater. B. If the number of digits is same in both the numbers, we compare the most significant digit (the left-most digit). The number with the higher digit at this place will be greater. C. If the left-most digits are same in both the numbers, we compare the next digit (towards the right), until we find a case where the digits differ. Step 2 Let us first compare the number of digits in 72337206 and 72334206: A. The number of digits in 72337206 = 8 B. The number of digits in 72334206 = 8 Step 3 Since the number of digits appears to be the same in both the given numbers, we will follow our next step to answer the question.
