Question

Find $0.4\times 0.6$ using decimal grid value method.

• A. 0.24
• B. 0.18
• C. 0.32
• D. 0.22

Answer 1

The correct option is A 0.24

First shade 6 rows in the grid in maroon color to represent 0.6. Shade 4 coloumns in the grid in green color to represent 0.4 of 0.6.

$\frac{6}{10}$

${\frac{4}{10}}^{th}of\frac{6}{10}$

Now 24 squares represents the common portion. This represents the 24 hundredths or 0.24.

Hence $0.4\times 0.6=\mathrm{0.24.}$
