3 part ratio and dealing with decimals
To work out ratios with decimals
Get rid of the decimal.
(We only work in integers.)
Keep multiplying all 3 ratios by 10 until decimal disappears.
Simplify the following ratio with decimals.
Multiply all 3 ratios by `10`
Because there is still a decimal in the ratio continue multiplying all 3 ratios by `10`.
Now we have removed the decimals we can now simplify `300:240:45`
(see our section on 3 part ratios - simplify integers)
`2`, `3`, `4`, `5.......` The first number that will divide into all of the ratio numbers is `3`.
`3` will not divide into these numbers again, the next number that will is `5`.
This ratio will not divide down any further so the answer is.
