Question

(0,5:1,25+ 7/5 :1 целая 4\7 -3\11) *3
___________________________
(1,5+1\4) : 18 целых 1/3

Answer 1

1.0,5÷1,25=0,4
2. 7/5÷1 4/7=7/5×7/11=49/55
3. 0,4+49/55=4/10+49/55=2/5+49/55=71/55
4. 71/55-3/11=38/55
5. 38/55×3=190/55=38/11
6. 1.5+0,25=1,75 (1,75= 1 75/100=7/4)
7. 7/4÷55/3=7/4×3/55=21/220
8. 38/11÷21/220=38/11×220/21=760/21 ~=36,1
