Answer:
The model represents the expression:
A. 7/8 ÷ 1/8
Step-by-step explanation:
In the question, the number line model represents 7/8 divided into 7 equal units. Each arrow represents a unit and there are a total of seven arrows.
The size of each unit is 1/8 as shown.
Showing that 1/8 divides 7/8 into 7 divisions:
7/8 ÷ 1/8
= 7/8 x 8/1
= 7/1 x 8/8
= 7 x 1
= 7
Hence, the number line represents seven divisions given by 7/8 ÷ 1/8.
