Multiply two fifths by two to get a common denominator. Then you will have 4 tenths plus three tenths. then add straight across and you will get seven tenths.
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.
It is one and nine twentieths.
3/10 + 7/10 = 1
seven and eight tenths. you have to change one half to five tenths and then add the whole numbers and then the fraction
four fifths is equal to eight tents, so three tenths plus eight tenths is eleven tenths, or one and one tenth
1 2/5
7/10+3/12=19/20
9 tenths
eight-tenths
seven-tenths
4/5 is what a half plus three tenths equals.
