13 of Bryan's money is equal to
45 of Adam's money.
Bryan has $108.
- 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 4.
LCM of 1 and 4 = 4
1 x 43 x 4 of Bryan's money =
4 x 15 x 1 of Adam's money
412 of Bryan's money =
45 of Adam's money
Amount that Bryan has = 12 u
Amount that Adam has = 5 u
12 u = 108
1 u = 108 ÷ 12 = 9
Amount that Adam has
= 5 u
= 5 x 9
= $45
(b)
Amount that Bryan has more than Adam
= 12 u - 5 u
= 7 u
= 7 x 9
= $63
(c)
Amount that they have altogether
= 12 u + 5 u
= 17 u
= 17 x 9
= $153
Answer(s): (a) $45; (b) $63; (c) $153
