Answer 1

Answer:

Step-by-step explanation:

1 first turn mixed fraction into improper fraction-

3/5 of 10/9+7/2

2 add mixed fraction by finding lowest common multiplication of denominators i.e 9 and 2 which is 9x2=18

3 now 10/9 = 20/18 and 7/2 = 63/18

  = 20+63/18 = 83/18

4 now let's come to 3/5 of 83/18

  = 3/5 x 83/18

  = 83/35

  = 2 13/35

number two in the answer is the whole number and 13/35 proper fraaction so write them together.

in point 4 while multiplying 3/5 and 83/18,  3 and 18 were reduced by 3 as they both come in 3's table ( 3x1-3, 3x-18)
