2/5 x 2/2 = 4/10 1/2 x 5/5 = 5/10 4/10 + 5/10 = 9/10 9 tenths
four fifths plus seven tenths is a very easy "equation" to solve. First you convert 4/5 into 8/10. Second you add 8+7 since you are adding. Lastly, since 8+7=15 the answer is 15/10. 15/10 is equal to 1 and 5/10 or 1 and 1/2 the answer is 1 & 1/2
