Ratio

Ratios

• Ratios are used to compare quantities
• You can find equivalent ratios by multiplying or dividing by the same number

Simplest form

• To write a ratio in its simplest form, find an equivalent ratio with the smallest possible whole number values

Problem solved

• If you use x to represent one part of the ratio, then you can write the length of the x as x
• Then form an equation and solve it to find x

Harder questions

• If the ratio contains decimals or fractions-multiply
• If the ratio has mixed units-convert to the smaller unit
