Question

Найдите модули 5, 3,5 , 1/6, -10,5, -11 , 1 целая 9/15, -105 ,105, 154 , -154, 9/16, -9/16

Answer 1

1) 3/5 × 4/9 + 1 1/3=1/5*4/3+1 1/3=4/15+1 5/15=1 9/15=1 3/5=1,6 

2) 1 1/4 × 2/5 - 1/3=5/4*2/5-1/3=1/4*2/1-1/3=1/2*1/1-1/3=1/2-1/3=
  =3/6-2/6=1/6

3)3/8:1/2 + 3 1/4=3/8*2/1+3 1/4=3/4*1/1+3 1/4=3/4+3 1/4=4

4)5/6 : 1/3 + 1 3/8=5/6*3/1+1 3/8=5/2*1/1+1 3/8=5/2+1 3/8=
  =2 1/2+1 3/8=2 4/8+1 3/8=3 7/8

5)1 2/5 × 5/7 +3/8=7/5*5/7+3/8=1+3/8=1 3/8

6)2 1/3 : 1 5/9 - 5/6=7/3:14/9-5/6=7/3*9/14-5/6=1/3*9/2-5/6=
  = 1/1*3/2-5/6=3/2-5/6=1 1/2-5/6=1  3/6-5/6=1- 2/6=1-1/3=2/3
