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.

School A has 480 students and 16 classrooms. School B has 192 students and 12 classrooms.
boyakko [2]

Answer:96

Step-by-step explanation:

A; 480/16 = 30 students per classroom

B: 192/12 =16 students per classroom

we need x such that \frac{480-x}{16} = \frac{192+x}{12}

which means

(480-x )* 12 should be equal to (192+x) * 16

5,760 - 12x = 3,072+16x

5,760 - 3,072 = 12x + 16x

2,688 = 28x

x = 96
