Which fraction is equal to .66
Nimfa-mama [501]
The fraction \frac{2}{3} = .66

To find this we need to realize that .66 can be converted to a fraction. The last 6 is in the hundredths place, so if we convert .66 to a fraction we will get: \frac{66}{100}

If we simplify this fraction as much as we can, we will get to \frac{2}{3}

To check this we can divide \frac{2}{3}. So, 2 ÷ 3 = .66, which is correct, so our answer is correct.

I hope this helped! Have an amazing day :)
