Answer:
q=1
Step-by-step explanation:
(I will use the cross multiplication method)
Step 1: multiply 20 x 4 (80)
Step 2: divide 80 by 40 (2)
Step 3: subtract 1 from the 2
4/1 = 40/20
If you want to check multiply 40 x 2 and 20 x 4
if they have the same answer then your answer is right.
40 x 2= 80
20 x 4=80
80=80
