Question 1

What is a ratio and how is it written?

Accepted Answer

A ratio compares the relative sizes of two or more values. It can be written in three different ways: with a colon (A:B), as a fraction (A/B), or in words ("A to B"). For example, if a recipe calls for 2 cups of flour and 3 cups of sugar, the ratio of flour to sugar is 2:3.

Question 2

How do you solve a proportion (A:B = C:D)?

Accepted Answer

A proportion states that two ratios are equal: A/B = C/D. To solve for a missing value, use cross-multiplication: multiply the numerator of one ratio by the denominator of the other. This gives the equation A × D = B × C. Divide by the remaining known coefficient to isolate the unknown variable. For example, to solve X:5 = 12:20, calculate X = (5 × 12) / 20 = 3.

Question 3

How do you simplify a multi-part ratio?

Accepted Answer

To simplify a multi-part ratio like 12:24:36, find the Greatest Common Divisor (GCD) of all the terms in the ratio. Then, divide each term by that GCD. The GCD of 12, 24, and 36 is 12. Dividing each by 12 gives the simplified ratio 1:2:3.

Question 4

How do you divide an amount into a ratio?

Accepted Answer

To divide a total amount (e.g. 1000) into a ratio (e.g. 2:3:5): first, add the ratio parts together to find the total number of shares (2 + 3 + 5 = 10). Next, divide the total amount by the sum of shares to find the value of a single share (1000 / 10 = 100). Finally, multiply each part of the ratio by the value of a single share: Part 1 gets 2 × 100 = 200, Part 2 gets 3 × 100 = 300, and Part 3 gets 5 × 100 = 500.

Question 5

What is the scaling factor in ratios?

Accepted Answer

The scaling factor is a multiplier or divisor used to scale a ratio up or down while keeping it equivalent. For example, scaling the ratio 3:4 up by a factor of 3 yields (3×3):(4×3) = 9:12. Both ratios represent the same proportional relationship.

Question 6

What is an equivalent ratio?

Accepted Answer

Equivalent ratios are different ratios that express the same proportional relationship. You can find equivalent ratios by multiplying or dividing both terms of a ratio by the same non-zero number. For instance, 1:2, 2:4, 5:10, and 50:100 are all equivalent ratios.

Question 7

Can ratios have decimals or fractions?

Accepted Answer

Yes, ratios can contain decimals or fractions, but they are typically written using whole numbers for simplicity. To convert a decimal ratio to a whole number ratio, multiply all terms by a power of 10 that eliminates the decimals. For example, 1.5:2.5 can be multiplied by 10 to get 15:25, which simplifies to 3:5.
