Answer:

2 miles 2 yards

Explanation:

There are 1760 yards in a mile, so you are effectively performing the division ...

(9185 380/1760) ÷ 4590

where the number in parentheses is a mixed number of miles.

You do this division the same way you do any mixed-number division. There are different possible methods you can use. One of them is to convert the mixed number to an improper fraction, then divide.

9185 380/1760 = 9185 19/88 = (88·9185 +19)/88 = 808299/88

Then this is divided in the usual way:


(808299)/(88)/4590=(808299)/(88\cdot4590)=(808299)/(403920)=2(459)/(403920)=2(1)/(880)

Finding the quotient and remainder is straightforward. Reducing the fraction involves finding common factors in the numerator and denominator. As it turns out, 459 is a factor of 403920, so the fraction reduces as shown.

Now, we need to convert 1/880 miles back to yards.

((1/880) mi) × (1760 yd/mi) = 2 yd

So, the quotient you seek is ...

2 miles 2 yards
