Question

D 7 1/7 :1 11/14 - 1 2/5 x 15/28
e 5 1/3 : 2 2/15 - [1 3/4 - 6 1/4 x 1/6]
f [1 1/8 + 3 5/6 x 5/23 ] - [4 1/3: 26 + 1 1/4

Answer 1

d 7 1/7 :1 11/14 - 1 2/5 x 15/28=50/7:25/14-1 2/5*15/28=4-7/5*15/28=4-3/4=13/4=3 1/4
e 5 1/3 : 2 2/15 - [1 3/4 - 6 1/4 x 1/6]=16/3:32/15-(1 3/4-6 1/4*1/6)=5/2-(7/4-25/4*1/6)=
=5/2-(7/4-25/24)=5/2-17/24=43/24=1 19/24
f  [1 1/8 + 3 5/6 x 5/23 ] - [4 1/3: 26 + 1 1/4]=9/8+23/6*5/23-(4 1/3:26+1 1/4)=
=9/8+5/6-(4 1/3:26+1 1/4)=47/24-(13/3:26+1 1/4)=47/24-(1/6+5/4)=47/24-17/12=13/24
