With ans..

Answer 1

see this question is very simple.
for the first one u divide 4 by 2 and then subtract 2( 4/2) from 5 which is 3.
again for the second one divide 9 by 3 and then subtract 3(9/3) from 9 which is 6.
so the question is repeating a similar pattern.
again for the last one, I divide 18 by 6 and subtract 3(18/6) by 7 which gives me 4.hence the answer is 4.

Answer 2

18÷6= 3
7-3=4
divide 2nd number by 1st number then subtract quotient from 3rd number
