GCSE Maths Ratios (help) :(

Please help me :frown: If your not then go away.
"There are some oranges and apples in a box
The total number of oranges and apples is 54.
The ratio of the number of oranges to the number of apples is 1:5
Work out the number of apples in the box."


Thank you.
Since it's 1:5, you know that 54 is divided into 6 equal lots. So you divide 54 by 6 (because both sides of the ratio add to 6) and get 9. This means that one one side there's 1 times 9, and on the other side there's 5 times 9 (45).
Since it's apples you want, the answer is 45.
Thumbs down for giving the right answer before anyone else... Yeah that makes sense.

That would be 54/6 as 5+1 as the ratio =6 then times 54/6 = 9 by 1 for oranges =9 and by 5 for apples = 45, so you have 45 apples and 9 oranges.

divide the total number of apples and oranges by six to get 9 (this is the number of oranges) there are five times as many apple as oranges so multiply 9 by 5 to get 45 apples.

Thank you.


1 add 5 =6
54 divided by 6 = 9
54-9= 45
45 is the number of apples :biggrin: Hope this helps!

Aw thanks man. Could you do this one for me (tell me how to do it) :
"Toby ivested £4500 for 2 years in a savings account.
He was paid 4% per annum compound interest.
How much did Toby have in his savings account after 2 years?"

For one year it would be 4500 X 1.04 (104%) right? And for the second year you would multiply the answer for the first year by 1.04 again. So the correct method is 4500 X 1.04^2.

well done to you too
Hey everyone, this thread is super, super old so I've locked it now. If you'd like to continue discussing the ratio of fruits, it's best to make a new thread in the maths forum :woo:

Good luck with your studies :h:
