Ratios
A jar contains 550 beans. Of all the beans, ⅖ are white beans and the rest are navy beans.
How many white beans are there? 220
Step 1 - First work out what ⅕ is. ⅕ = 110
Step 2 - Double it. 110+110=220
What is the ratio of white beans to navy beans? 2 : 3
If white beans are ⅖ then the navy beans will be ⅗. So the answer will be 2 : 3
How many navy beans are there? 330
Add 110 to 220 because 110 is ⅕ and 220 is ⅖, so all you have to do to get ⅗ is to add 110 to 220. 220+110=330
