Answer:
c = 80/3
Step-by-step explanation:
4:3 = c:20
Turn ratios to fractions.
4/3 = c/20
Cross multiply.
3 × c = 20 × 4
3c = 80
Divide both sides by 3.
(3c)/3 = 80/3
C is approx. 27
4 is to 3 as c is to 20 is a proportion to solve set 4/3=c/20 cross multiply to get 80=3c then divide to get 26.6666666666667 rounding this decimal up, you get 27
