Multiply each of the fractions by 1 to get them to have the same denominator.
1/4 x 3/3 = 3/12
1/3 x 4/4 = 4/12
New Equation:
3/12a + 4/12a + 8 = 22
now add up similar terms
7/12a + 8 = 22
subtract 8
7/12a = 14
multiply each side by your denominator
12(7/12)a=12(14)
7a=168
divide by 7
a = 24

in the computer lab there are 14 Apple computers and 16 PC computers. Approximately what percent of the computers are PCs?
ad-work [718]


So first we take the total number of computers. Which will be 14 + 16 = 30 computers.

Since we have 16 pc computers, we will divide 16 by 30 and multiply it by 100 to get the percentage:

So: (16/30) x 100

There are 53.33% PC computers in the computer lab.
