A and b share a the cost in a ratio of 3:2 the cost is £85, how much does a pay?

Answers

85/5 = 17
17x3 = 51
17x2 = 34
51:34
A has to pay £51 (and B pays £34)
This is how you work it out: A:B
                                         3:2
3+2=5,  85/5 = 17 (this is what you would have to pay if your part of the ratio was 1)
therefore, to find what A pays, you times the part 1 by 3 (as the ratio is 3:2)
17 x 3 = 51
(likewise, 17x2= 34 which is what B has to pay)

Wayne has a recipe on a 3 inch by 5 inch index card that he wants to    enlarge to 15 inches long. How wide will the enlargement be?Also I'm really sorry for the people that I just put random things that's why there is more pts on this question once again I'm sorry for the random things that I put hope you guys would forgive me okay bye.

Answers

I'm not completely sure which way they would like for you to do it
but anyways

3 to 15 is a times 5
so 5 times 5 is 25
so a possible width can be 25
as in 15 by 25

or

5 to 15 is times 3
so 3 times 3 is 9
so a possible width can be 9
as in 15 by 9

I personally think 25 inches wide would be the better answer
