13 of Adam's money is equal to
58 of Bryan's money.
Adam has $240.
- How much does Bryan have?
- How much does Adam have more than Bryan?
- How much do they have altogether?
(a)
Make the numerators the same using the LCM of 1 and 5.
LCM of 1 and 5 = 5
1 x 53 x 5 of Adam's money =
5 x 18 x 1 of Bryan's money
515 of Adam's money =
58 of Bryan's money
Amount that Adam has = 15 u
Amount that Bryan has = 8 u
15 u = 240
1 u = 240 ÷ 15 = 16
Amount that Bryan has
= 8 u
= 8 x 16
= $128
(b)
Amount that Adam has more than Bryan
= 15 u - 8 u
= 7 u
= 7 x 16
= $112
(c)
Amount that they have altogether
= 15 u + 8 u
= 23 u
= 23 x 16
= $368
Answer(s): (a) $128; (b) $112; (c) $368
