Answer 1

Answer:

1)(3*4+3)/4+?=4

or,15/4+?=4

or,?=4-15/4

or,?=(4*4-15)/4

or,?=1/4

2)12-(2*4+3)/4=?/4

or,12-11/4=?/4

or,(12*4-11)/4=?/4

or,[(48-11)/4]*4=?

or,?=37

3)say,the missing number is ' x'

so, (9*8+3)/8-(2*8+1)/8=(x*4+1)/4

or,75/8-17/8=(4x+1)/4

or,([[(75-17)/8]*4]-1)/4=x

or,x=7
