Question

117,5*4/17-11 2/3 +(10 2/25-8 7/15):11/45 помогите решить пожалуйстааа

Answer 1

1) 10 2/25 - 8 7/15 = 10 6/75 - 8 35/75 = 9 81/75 - 8 35/75 = 1 46/75
2) 117,5 * 4/17 = 1175/10 * 4/17 = 2350/85
3) 1 46/75 : 11/45 = 121/75 * 45/11 = 33/5
4) 2350/85 + 33/5 = 2350/85 + 561/85 = 2911/85 = 34 21/85
