Question

Help pls 10-11 plsssssss

Answer 1

10. First find the common denominator for 7/8 and 9/10. I personally chose 35/40 and 36/40. Add the two fractions up to get a irregular fraction, which is 71/40. To then get a regular fraction, subtract 40 from 71 (which leaves you with a 1 in the ones place), then take the remaining number and put it like this: 1 31/40

Answer 2

10. 7/8 + 9/10 = 35/40+ 36/40 which equals 71/40 = 1 31/40 is the answer
11. 1/4+2/5= 5/20+8/20 = 13/20 which is the answer
