Why is the ratio 1 to 3 the same as the fraction 1 over 4?
Karaarthurholtz
The two ratios, 16 to 9 and 4 to 3, are not the same number. Dividing the first number in the ratio by the second number in the ratio provides a decimal equivalent value. 16 divided by 9 does not equal 4 divided by 3.
16 to 8 and 4 to 2 however are examples of equivalent ratios. When the first number in the pair is divided by the second number in the pair, the answers are equal.
Remember that equivalent ratios describe the proportion of the number of one thing to the number of another thing rather than the things themselves.
So, the proportion of 16 birds to 8 birds is the same as the proportion of 4 apples to 2 apples, that is 2 to 1.
