Exercise 7.2

 

1). Draw number lines and locate the points on them :

a). ½, ¼, ¾, ⁴/₄

we will divide each unit into 4 equal parts.

A ↔ ½

B ↔ ¼

C ↔  ¾

D ↔ ⁴/₄

 

b). ¹/₈, ²/₈, ³/₈, ⁷/₈

we will divide each unit into 8 equal parts.

A ↔ ¹/₈

B ↔ ²/₈

C ↔ ³/₈

D ↔ ⁷/₈

 

c). ²/₅, ³/₅, ⁸/₅, ⁴/₅

we will divide each unit into 5 equal parts.

A ↔ ²/₅

B ↔ ³/₅

C ↔ ⁸/₅

D ↔ ⁴/₅
