Jane and Kate share $240 in the ratio 5:7

(a) Show that Kate receives $140.

(b) Jane and Kate each spend $20.

Find the new ratio Jane’s remaining money:Kate’s remaining money. Give your answer in its simplest form.

5 : 7 means that there are 12 equal parts of the $240

And Kate gets 7 of these....so......

(7/12) * $240 = 7 * $20 = $140

And Janee has $100

If they each spend $20 there is $200 left

Jane has $80 and Kate has $120

So

80 : 120 =

8 : 12 =

2 : 3
