Emma and Olivia had the same amount of money at first. After Emma gave $450 to her nephew, Olivia had 6 times as much money as Emma. How much did Emma have in the end?

| Before |
1x6 =

1x6 =
6 u |

- $450 |

| After |
1 u |
6 u |
The amount that Olivia had at first and in the end remains unchanged. Make the amount that Olivia had the same. LCM of 1 and 6 is 6.
Amount that Emma gave to her nephew
= 6 u - 1 u
= 5 u
5 u = 450
1 u = 450 ÷ 5 = 90
Amount that Emma had in the end
= 1 u
= $450
Answer(s): $450
