Before |
1x5 = 5 u |
1x5 = 5 u |
7x5 = 35 u |
45 u |
Change |
- 4 u |
No change |
+ 4 u |

After |
1x1 = 1 u |
5x1 = 5 u |
39 u |
45 u |
Zara and Sabrina shared
29 of the money equally.
Fraction of the money that Zara and Sabrina each had
=
29 ÷ 2
=
29 x
12 =
19 The amount that Sabrina had remains unchanged. The amount that Sabrina had is the unchanged quantity. Make the amount that Sabrina had the same. LCM of 1 and 5 is 5.
The amount that Zara and Sabrina had at first is the same.
Total amount that they had at first
= 5 u + 5 u + 35 u
= 45 u
45 u = 585
1 u = 585 ÷ 45 = 13
Amount that Zara gave to Lucy
= 5 u - 1 u
= 4 u
= 4 x 13
= $52
Answer(s): $52
