Question

Help. I have no clue how to do this and neither do any of my classmates

Answer 1

A.) 1350 miles

Explanation:

So, you know the amount of 1/2 of an in. is equal to 200 miles on the map. Next, you have to change the 1/2 to be a common denominator, so you change it to 4/8. Now, you have 4/8=200 mi. Okay, so, to get your answer, you divide the equation here __^^^ by 4 to get 1/8=50 miles. Then, you turn 3 and 3/8 into an improper fraction, which is 27/8, and do 50 times 27 to get 1350 miles.

Here's the math work:

`key; (1)/(2):200\\(1)/(2)=200\\(4)/(8)=200((4)/(8)=200)/(4)\\(1)/(8)=50\\3(3)/(8)=(27)/(8)\\if (1)/(8)=50, then (27)/(8)=?\\27*50=1350 miles`
