Question

Olivia and Jamie share

sweets in the ratio 3: 7. If
Olivia gets 27 how many
sweets does Jamie get?

Answer 1

63

Explanation:

you have set them up so you can cross multiply.

(3 * x) = (7 * 27)

3x = (189)

to solve for x we need to isolate the variable, so divide both sides by 3:

x = 63

Answer 2

jamie gets 63

Explanation:

27(olivias sweets)/3=9

9*7=63

=63
