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
