"of the computers" tells you that the answer is a percent of ALL of them.
How many computers are there altogether ? (36 + 54) = 90 computers.

How many laptops are there ? ===> 54

What percentage of the total of 90 is 54 ?

54/90 = 0.6 = <em>60% </em>.

First find the total number of computers
which is 36+54= 90 total number of computers
use ratio and proportion
56/90= x/100
cross multiply
90x=5400
x= 60% of the computers are laptops

hope this helps

Angle B and angle C are complementary. If angle B is five times the size of angle C what is the measurements of both angles.

faltersainse [42]

Step-by-step explanation:

Let Angle C be x

So angle B will be 5x

Since they both are complementary, we can come up with this equation.

x+5x=90 degrees

6x=90 degrees

x=90/6,x=15

Measures of Angles

Angle C=x=15 degrees

Angle B=5x=5*15=75 degrees
