Ratios
I have a Key Stage 3 book, yet it doesn't tell me anything about how to work out Ratios..
The ratio of weight of Andy to Jan is 7:5. Jan has a weight of 95kg, how much does Andy weigh?
In a recipe the ratio of flour to butter is 2:3. How much flower is needed to mix with 240g of butter?
Can someone explain please..

A:J = 7:5
Every 7 kg Andy weighs means that Jan weighs 5kg
So if Andy weighed 42kg (6x7)
Then Jo would weigh 30kg (5x5)

7:5
?:95
5 x 19 = 95
So we do 7 x 19 to get your answer

Eg ..
Flour: Butter
2:3
?:240g
240/3 = 80 ( =1)
So to get 2 .. 2 x 80 =160
160:240
I Hope this helps

you said here do 5 x 19 = 95
then 7 x 19 to get your answer this equals 133
so what is it...

I have another ratio question..
Split 500m in the ratio 1:4
& another
Split 4.8kg in the ratio 1:5
Do I work these out the same as the one before?

First one:
Add the parts of the ratio
1 + 4 = 5 parts
Divide 500 m by 5 (the number of parts)
1 part is 100 m
If 1 part is 100 m how big is 4 parts?

well 400 m would be four parts?
