5/11 and 6/12
- Cross multiply.
- 5 * 12 = 11 * 6
- 60 = 66
- This is UNTRUE, so this does <em>not </em>form a proportion.
7/13 and 21/39
- Cross multiply.
- 7 * 39 = 13 * 21
- 273 = 273
- This is TRUE, so this forms a proportion. Let's keep going to make sure that this is our answer.
8/14 and 24/30
- Cross multiply.
- 8 * 30 = 14 * 24
- 240 = 336
- This is UNTRUE, so this does <em>not </em>form a proportion.
10/20 and 20/30
- Cross multiply.
- 10 * 30 = 20 * 20
- 300 = 400
- This is UNTRUE, so this does <em>not </em>form a proportion.
Your answer is <u>7 : 13 and 21 : 39</u> are a pair of ratios that form a proportion.
