Eric needs 1/2 deck of playing cards for a magic trick. He only has 2/7 of a deck. What fraction of a deck does Eric still need?

tatyana61 [14]

Answer: Eric still needs $\frac{3}{14}$ of a deck.

Step-by-step explanation:

You know that:

- Eric need 1/2 deck of playing cards.

- Eric has 2/7 of a deck.

Therefore, to find the fraction of a deck that Eric still needs, you must subtract 1/2 and 2/7:

- Find the least common multiple of the denominators:

$2=2*1\\7=7*1$

$LCM=2*7*1=14$

- Now, you can make the subtraction:

$\frac{(7*1)-(2*2)}{14}=\frac{7-4}{14}=\frac{3}{14}$

Therefore, he still needs $\frac{3}{14}$ of a deck.
