You simplify a fraction by finding it's greatest common factor. A greatest common factor is what both numbers are divisible by. If they can both be divided by two, then you've simplified them a little bit. Keep going until you can't find a common number that can be divided by the two, and you've got your simplified fraction. For example, 10/5 = 1/2 since both 10 and 5 is divisible by 5.
20 yards
take 5 1/8 and make that into 40/8 and then you will divide 40 into 8 and it = 5 so then you do 4x5=20
First you would have to find the distance it's going per hour.

You will then get the answer of 200 m/hr. You can then plug in 200 m/hr to find how far the jet could fly in 10 hours

You're final answer should be 2,000 miles
10 3/5=10.6
10.6+12.5=23.1
35.0-23.1=11.9
It is 11.9 miles from Chester to Durbin.
Answer:
f-¹(x) = 2x – 8
f-¹(4) = 2(4) – 8 —> f-¹(4)= 8 - 8 =0
