7 : 28 = 2 : 8
That means that the ratio 7 / 28 is equal to the ratio 2 : 8.
You can verify the equality by simplifying to the simplest form:
7 : 28 = 1 / 4 simplest form
2 : 8 = 1 / 4 simplest form, then the proportion is right.
In words that is 7 is to 28 as 1 is to 4 ← answer
2) Proportion b.. 3⁄1 = 18⁄6
In words: 3 is to q as 18 is to 6 ← answer
You can verify the proportion by simplifiying the second fraction:
18 / 6 = [18 / 6] / [ 6 / 6] = 3 / 1
3) Proportion c. 9 : 72 = 2 : 16
In words: 9 is to 72 as 2 is to 16 ← answer
Proove the proportion:
9 / 72 = 1 / 8
2 / 16 = 1 / 8
4) Proportion d. 81⁄9 = 45⁄5
In words: 81 is to 9 as 45 is to 5 ← answer
Proove it:
81 / 9 = 9
45 / 9 = 9
