Пошаговое объяснение:

1) 3/8×4/5÷9/10=1/3

3/8×4/5=3/10

3/10÷9/10=3/10×10/9=1/3

2)6/7÷3/5×1 2/5= 150/147 1 2/5=7/5

3/5×7/5=21/25

6/7÷21/25=6/7×25/21=150/147

3) 2 2/11× 1 3/8÷3/4= 4

2 2/11×1 3/8=24/11×11/8= 3

3÷ 3/4=3×4/3=4

4) 11/23× 3 2/7÷ 5 1/2=2/7

11/23×23/7=11/7

11/7÷11/2=11/7×2/11=2/7

5)3/5×(2 2/3÷3 1/5)= 1/2. бұл жерде бөлу жақша ішінде болғандықтан бөлу бірінші орындалады

2 2/3÷3 1/5=8/3÷16/5=8/3×5/16=5/6

3/5×5/6=1/2

6) 1 1/8×(9 1/3÷1 3/4)=22/3

9 1/3÷1 3/4=28/3÷7/4=28/3×4/7=16/3

11/8×16/3=22/3
