- Divide the total amount by the total number of shares.
- Multiply by the number of shares required.

**How do you solve a 3 way ratio problem?**

To calculate a ratio of 3 numbers, we follow 3 steps:

- Step 1: Find the total number of parts in the ratio by adding the numbers in the ratio together.
- Step 2: Find the value of each part in the ratio by dividing the given amount by the total number of parts.
- Step 3: Multiply the original ratio by the value of each part.

### How do you work out ratios on a calculator?

Press the divide button, enter the greatest common factor and press the equals button. Write this number down. In this example, you work out 84 รท 12 = 7. Express your ratio using the number in Step 3 and the number in Step 5.

### How do you calculate ratios with examples?

What is the easiest way to calculate a ratio?

- Find the total number of parts โ if the ratio is 3:2, the total is 5.
- Divide the figure by the number of parts to find the sum of one part โ $30 divided by 5 = 6. One part is 6.
- Multiply each number in the ratio by the value of one part โ 3 x 6 and 2 x 6.

**What are the slope-intercept form of each equation?**

The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It’s usually easy to graph a line using y=mx+b. Other forms of linear equations are the standard form and the point-slope form.

## How do ratios work in math?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)
