Answered by Ms. Sue
What is the map scale?

Answered by T. Reed
1/8 in. = 10 mi.
1 1/8 in. = ? mi.
And you give the formula Ms. Sue
Answered by Ms. Sue
One way to solve this is by using a proportion. Cross multiply and solve for x.

(1/8) / 10 = (1 1/8) / x

1/8x = 11 1/4

x = (11 1/4) / (1/8)

x = 45/4 * 8 = 90

So Ms. My answer would be 90? But I'm still having a hard time understanding how you got your answer.
Answered by Ms. Sue
Yes, the answer is 90.

Another way to approach this is to note that 1 1/8 is 9 times 1/8. So 9 * 10 = 90.
