Ellen's carton is 3/7 full. Fern's carton is 3/10 full. Kyle's carton is 3/4 full Who has the least amount left in their carton?
Change them all to decimals.
3/7 = 0.43
3/10 = 0.30
3/4 = 0.75
0.30
To find out who has the least amount left in their carton, we need to compare the fractions representing the amount of each carton that is full.
Ellen's carton is 3/7 full.
Fern's carton is 3/10 full.
Kyle's carton is 3/4 full.
To compare fractions, we can find a common denominator for all the fractions involved. In this case, the least common denominator is 140, which is the product of 7, 10, and 4.
Multiplying the numerator and denominator of each fraction by the same value will give us equivalent fractions with a common denominator of 140:
Ellen's carton: (3/7) * (20/20) = 60/140
Fern's carton: (3/10) * (14/14) = 42/140
Kyle's carton: (3/4) * (35/35) = 105/140
Now we can see that Ellen's carton has 60/140 left, Fern's carton has 42/140 left, and Kyle's carton has 105/140 left.
To compare the fractions, we can look at the numerators since the denominators are the same:
60 < 105 < 42
Therefore, Fern's carton has the least amount left in their carton with 42/140 full.
