14 of her marbles. What fraction of the orange marbles was Jaslyn left with?
|
Pink |
Orange |
Total |
Comparing pink marbles and orange marbles at first |
1x5x2 = 10 u |
1x5x2 = 10 u |
2x5x2 = 20 u |
Before |
5x2 = 10 u |
10 u |
4x5 = 20 u |
Change |
- 3x2 = - 6 u |
- 9 u |
- 1x5 = - 15 u |
After |
2x2 = 4 u |
1 u |
3x5 = 5 u |
The number of pink marbles at first is repeated. Make the number of pink marbles the first the same. LCM of 5 and 1 is 5.
The total number of marbles at first is repeated. Make the total number of marbles at first the same. LCM of 10 and 4 is 20.
Number of orange marbles that Jaslyn was left with
= 5 u - 4 u
= 1 u
Fraction of the orange marbles that Jaslyn was left with =
