Julie makes $7.65 for 1 hour. We know she earned $24.48 so how many hours did she work to earn that? you could set it up like this

1hr = X (hrs)
$7.65 $24.48 (money earned) now cross multipy

7.65 * x = 1*24.48
7.65x=24.48 (now we want x alone)

7.65x=24.48 (you must divide both sides by 7.65 to get x alone)
7.65 7.65
now any number divided by itself is 1 so
1x is automatically written like this

x=24.48
7.65 now divide 24.48 by 7.65 to get the answer
x=3.2 hours that's your answer. She worked 3.2 hours to earn $24.48

You need to find the GCF (greatest common factor) of 45 and 90, which is 45.

45 times ? gets you 45

? would be 1

45 times 1 equals 45.

45 times ? gets you 90

? would be 2

45 times 2 equals 90

45(1+2) = 45+90 = 135

Step-by-step explanation:

Correct Question : Tom has a scale model of his car. The scale factor is 1 : 12. If the actual car has 16-inch wheels, what size are the wheels on the scale model?

We have , The scale factor is 1 : 12. We need to find If the actual car has 16-inch wheels, what size are the wheels on the scale model .Let's find out:

Ratio of size of wheels to actual size of wheels is 1:12 , but actual car has 16-inch wheels So ,

⇒ $\frac{1}{12} = \frac{x}{16}$ { x is size of wheel in scale model }

⇒ $\frac{1(16)}{12} = \frac{x}{16}(16)$

⇒ $x =\frac{16}{12}$

⇒ $x =\frac{4}{3}inch$

Therefore , $x =\frac{4}{3}inch$ is the size in wheels on the scale model .
