Question

A 4/5 x (2/3+7/5)

B (9/10 x 1/3) (4/5 ÷ 1/2)

C (8/7 ÷ 3/9 ) + (9/4 - 1/2 )


D (7/10 x 45/3 ) + ( 13/5 ÷ 14/4)

Answer 1

a) = 4/5(10+21/15)
   = 4/5(31/15)
   =124/75
b)=(9/30)(8/5)
   =(3/10)(8/5)
  =24/50
c) = (72/21)+(9-2/4)
    =(24/7)+(7/4)
   =24/7+7/4
   =96+49/28
  =147/28
d) =315/30+52/70
=22050+1560/2100
=23610/2100
=2361/210
