What is three fifths plus seven tenths?

Answer 1

To add three fifths and seven tenths, we need to find a common denominator. The least common multiple of 5 and 10 is 10, so we convert three fifths to six tenths. Therefore, six tenths plus seven tenths equals thirteen tenths. Thirteen tenths can be simplified to one and three tenths, or 1.3 as a decimal.

Answer 2

3/5 + 7/10 = 1 3/10 or one and three tenths. Expressed as a decimal, this is equal to 1.3.
