Question

Plz can someone help me, Ive been stuck on these for so long Thank you so much!

1. n ÷ 4 = 4
2. 144 ÷ m = 12
3. r ÷ 3 = 7
4. a ÷ 2 = 18

Answer 1

1) 16 ÷ 4 = 4

2) 144 ÷ 12 = 12

3) 21 ÷ 3 = 7

4) 36 ÷ 2 = 18


p.s - what I did was I multiplied the numbers which were in the equation to get the variable, but for number 2 you don’t multiple, you divide 144 by 12.
