What is the sum of 2/10 + 6/100

13/50

Step-by-step explanation: To add these 2 fractions together, 2/10 + 6/100, we need a common denominator. The common denominator is simply the least common multiple for the 2 denominators which in this case is 100.

In order to get a denominator of 100 in the first fraction, we must multiply our denominator of 10 by 10.

The problem is we can't just multiply the denominator of a fraction bt 10 because that changes its value.

However if we also multiply the numerator of the fraction by 10, we're actually multiplying the fraction by 10/10 which is 1 and when we multiply anything by 1, it doesn't change its value. So our first fraction becomes 20/100. Notice that 20/100 has the same value as 2/10.

Since 6/100 already has a denominator of 100, we leave it.

So we have 20/100 + 6/100.

To add like fractions, we add across the numerators and keep the same denominator.

So 20/100 + 6/100 gives us 26/100.

Since the fraction 26/100 is not in lowest terms, we divide the numerator and denominator by 2 to get the equivalent fraction 13/50.
