Question

Помогите решить г). спасибо

Answer 1

1) 3 15/28 : 9/28 = 99/28 : 9/28 = 11
2) 1 : 1 10/49 = 1 : 59/10 = 10/59
3) 11 - 10/59 = 10 49/59
4) 2/5 • 10 49/59 = 2/5 • 639/59 = 1278/295
5) 1278/295 : 2 = 1278/590
6) 21 2/59 - 1278/590 = 2480/59 - 1278/590 = 24800/590 - 1278/590 = 23522/590 = 39 512/590

Answer 2

1) 3 15/28:9/28=99/28*28/9=11
2) 1:59/49=1*49/59=49/59
3)11/1-49/59=649-49/59=600/59
4) 2/5*600/59=1200/295=240/59
5) 240/59*1/2=240/118=120/59=2 2/59
6) 21 2/59-2 2/59=19
