Question

Help David with his homework by calculating the value of B:

• A. 0.48
• B. 0.68
• C. 0.84
• D. 0.86

Answer 1

The correct option is A 0.48

To find the value of B, we first find the value of A.

A = 0.12 $\times$ 5

Calculating 0.12 $\times$ 5 using visual models, we get:


Total divisions = 60

∴ 0.12 $\times$ 5 = 0.6

Hence, A = 0.6

Now, it is given that, A $\times$ 0.8 = B

So, 0.6 $\times$ 0.8 = B

Calculating 0.6 $\times$ 0.8 using the grid model, we get:


∴ The value of B is 0.48.
