Choose the correct proportions.

6, 15, 2, 5

a) 2:6 = 5:15
b) 2:5 = 6:15
c) 5:2 = 6:15
d) 2:5 = 15:6

A) 2:6=5:15

Step-by-step explanation:

2:6=1/3

5:15=1/3 then

2:6=5:15(=1/3)

a) 2:6 = 5:15

Step-by-step explanation:

Option A (2:6 = 5:15) is the correct option, with knowledge of equivalency of fractions, you will easily solve problems like this.

Let's solve it:

we must break all fractions to it's lowest term first.

2/6 = 1/3 (that is dividing both the numerator and the denominator by 2)

2/2= 1

6/2 = 3

Hence 2/6 = 1/3 (proved!)

Let's move to the other fraction:

5/15 = 1/3

HOW?

Divide the numerator and the denominator by 5.

5/5 = 1

15/5 =3

Therefore 2:6 = 5:15 = 1/3
