Explain the strategy you used to solve this problem?

10% of 20

I multiply: 0.1 * 20

put it like this


100% is 20 then
10% is x

now you just have to cross multiply
so u get .....

100x=(20) * (10)
therefore, x=(20)*(10)/100
x=2

x=2

To solve the problem of finding 10% of 20, the strategy I used is to multiply the number by the percentage value in decimal form.

First, I converted 10% to decimal form by dividing the percentage by 100. In this case, 10 divided by 100 equals 0.10.

Then, I multiplied 0.10 by the number 20. The calculation is 0.10 multiplied by 20, which equals 2.

Therefore, the answer to 10% of 20 is 2.
