Math Tutor Solution: 122/100 as a decimal is 1.22
Methods
Method 1 form a Math Tutor – Explanation using the division method:
One method to convert 122/100 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 122 by the denominator 100:
122 (numerator) ÷ 100 (denominator) = 1.22
And there you go! We got 1.22 as the answer when you convert 122/100 to a decimal.
Method 2 from a Math Tutor – 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 100 a power of 10, we need to multiply by 1 (100 * 1 = 100. Since we multiplied the denominator by {m}, we also need to multiply the numerator by {m} too:
