5. A proportion is when two or more ratios are equivalent to each other and can be simplified to the same thing. For example, 1:3 and 2:6, or 1/2 and 5/10.
3:6 simplifies to 1:2. 5:10 simplifies to 1:2. This pair is a proportion and should be selected.
4:12 simplifies to 1:3. 6:18 simplifies to 1:3. This is also a proportional relationship.
20:5 simplifies to 4:1. 10:3 cannot be simplified any further without having a decimal. This is not proportional.
24:36 simplifies to 2:3. 8:9 cannot be simplified, This isn't a proportion.
6. 2:3 = 8:p
2 × 4 = 8
3 × 4 = 12
p = 12
Let's simplify 8:12 to make sure it's equivalent to 2:3.
8 ÷ 4 = 2
12 ÷ 4 = 3
2:3
Hope this helps!
