Answer: 3/6
Step-by-step explanation:
Anytime you want to figure out the ratio, you divide the denominator (bottom number) by the numerator (top number).
First divide 14 by 7 and you get 1/2 (or 0.5 if you used the calculator). Now do this for each of the others until one matches or has the same ratio.
a) 5/12 : 12 ÷ 5= 2.4 * Not a match
b) 2/5: 5 ÷ 2= 2.5 * Not a match
c) 4/9: 9 ÷ 4= 2.25 * Not a match
d) 3/6: 6 ÷ 3 = 0.5 This is a MATCH!!!
