Solution: 90/10 as a decimal is 9MethodsMethod 1 – Explanation using the division method:One method to convert 90/10 to a decimal is by using the division method. Before we move ahead to the method, here is a quick recap on fractions: A fraction is a number representation that is broken down into two parts - the number on top is called the numerator, and the number on the bottom is called the denominator. To get a decimal using the division method, simply divide the numerator 90 by the denominator 10:90 (numerator) ÷ 10 (denominator) = 9And there you go! We got 9 as the answer when you convert 90/10 to a decimal.Method 2 – Explanation using the factors of 10 method:In this method, we will convert the denominator into a power of 10 and then our fraction will be easier to calculate. If the denominator is a factor of a power of 10, like 2, 4, 5, 8, 10, 16, 20, 25, 40, 50 and so on, then we can convert it into a power of 10.In order to make 10 a power of 10, we need to multiply by 1 (10 * 1 = 10. Since we multiplied the denominator by {m}, we also need to multiply the numerator by {m} too:90∗110∗1=9010=9\frac{90 * 1}{10 * 1} = \frac{90}{10} = 910∗190∗1=1090=9And finally, you get 9 as your answer when you convert 90/10 to a decimal.Practice more problems!All it takes to be better at something is some practice!
