13 of Bryan's money is equal to
35 of Adam's money.
Bryan has $288.
- How much does Adam have?
- How much does Bryan have more than Adam?
- How much do they have altogether?
(a)
Make the numerators the same using the LCM of 1 and 3.
LCM of 1 and 3 = 3
1 x 33 x 3 of Bryan's money =
3 x 15 x 1 of Adam's money
39 of Bryan's money =
35 of Adam's money
Amount that Bryan has = 9 u
Amount that Adam has = 5 u
9 u = 288
1 u = 288 ÷ 9 = 32
Amount that Adam has
= 5 u
= 5 x 32
= $160
(b)
Amount that Bryan has more than Adam
= 9 u - 5 u
= 4 u
= 4 x 32
= $128
(c)
Amount that they have altogether
= 9 u + 5 u
= 14 u
= 14 x 32
= $448
Answer(s): (a) $160; (b) $128; (c) $448
