A scale model of a car is 10 in. long. The actual car is 15 ft long. What is the scale of the model?
nikklg [1K]
Oh this question is kinda tricky. At first glance it’s 1 : 1.5 but notice the units. The model car is 10 inches long and the actual car is 15 feet long.

I think you know where to go from there, but 15 feet * 12 inches = 180 inches.

10 : 180 simplifies to 1 : 18 inches

8/7 divided by 5/8.
maksim [4K]

Answer:

64/35

Step-by-step explanation:

To divide fractions, multiply the first fraction by the second fraction's reciprocal.

The reciprocal of a fraction is just the top and bottom number switched.

So the reciprocal of 5/8 would be 8/5.

Now, you can multiply 8/7 by 8/5.

This gives you 64/35.

And that's it!
