When a whole number is divided by a unit fraction the result is each unit being divided into smaller parts. Dividing each unit of 6 into four equal parts results in 24 equal parts of one- fourths, so the qotient will be a whole number greater than the dividend. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 1 1 1 2. Dividing into 6 equal parts results in a unit fraction of because each of the whole is 4 24 4 divided into 6 equal parts. 1 4 Task 2 1 1. 32 ÷=64 2 1 1 2. ÷=2 4 8 1 1 3. ÷=3 2 6 1 4. 32 ÷=128 4 Task 3 C STAAR® Review To Go: Grade 5 ©2016 Region 4 Education Service Center All Rights Reserved Name: _________________________ Date: __________ Task 1: Representing and Explaining Division with Unit Fractions 1.
