Question

Find the 0.53 - 0.09 using decimal grid models.

• A. 0.44
• B. 0.54
• C. 0.46
• D. 0.48

Answer 1

The correct option is A 0.44



Here, $0.53=\frac{53}{100}$ and $0.09=\frac{9}{100}.$

First shade the region 0.53 then cross out 0.09, which is $\frac{9}{100}$ from the shaded area. The left out shaded region without cross marks is the difference.

So, 0.53- 0.09 = 0.44.
