Question

If 10% of a number equals 2, find 40% of that number.

Answer 1

Let's call the number we're trying to find "x".

We know that 10% of x is equal to 2.

So, we can set up the equation:

0.1x = 2

To solve for x, we can divide both sides by 0.1:

x = 2 ÷ 0.1

x = 20

Now that we know x is 20, we can find 40% of that number:

40% of 20 = 0.4 x 20 = 8

Therefore, 40% of that number is equal to 8.

Answer 2

8

Explanation:

40% is 4 times 10%, so the number is 4 times greater.

4 × 2 = 8

Answer: 8
