Question

Find the 0.65 - 0.13 using decimal grid models.

• A. 0.52
• B. 0.62
• C. 0.55
• D. 0.56

Answer 1

The correct option is A 0.52


Here, $0.65=\frac{65}{100}$ and $0.13=\frac{13}{100}.$

First shade the region 0.65 then cross out 0.13, which is $\frac{13}{100}$ from the shaded area. The left out shaded region without cross marks is the difference.

So, 0.65- 0.13 = 0.52.
