No 10/15 is 2/3
Convert the fraction parts to like terms, in this case fifteenths. 2 thirds is 10 fifteenths. 1 fifth is 2 fifteenths. So the final resuls is 1 and 10 fifteenths minus three fifteenths which is 1 and 7 fifteenths.
1 and 9/10
3/5, 6/10, 12/20
12 fifteenths (sure?)19 fifteenths = 10 fifteenths (2/3) + 9 fifteenths (3/5)
9/15-10/15 = -1/15
Well, darling, 7 tenths is the same as 10 fifteenths, so you're basically adding 10 fifteenths to 4 fifteenths, which gives you 14 fifteenths. So the answer is 14/15. Math doesn't have to be boring, honey!
3/4 x 10 = 7.5
85 dimes = 85*10 cents = 85*10/25 quarters = 34 quarters.
10/4 - 3/4 = 7/4 = one and three quarters
First we convert them into similar units, giving us 10 fifteenths and 12 fifteenths. Together that is 22 fifteenths or 1 and 7 fifteenths.
2/3
Three quarter of 12 is 9
