keeping in mind that there 60 seconds in 1 minute, and about 1.609 kilometers in 1 mile.
Answer:
2 1/20
Step-by-step explanation:
It was trick math problem and I was working it out, so mad I didn't pay attention to the numbers more closely. :)
There are two 3/8 but one is negative so they cancel each other out
So you have now (-4/5) + 5/4
Find the least common multiple they have.
In this case 20
-4/5 = x/20 = 16/20
5/4 = x/20 = 25/20
So now add them both together
16/20 + 25/20 = 41/20
Find the least common factor for both the denominator and numerator of 41/20
41 is a prime number so
41/20 is an improper fraction
Divide 41 by 20 to get 2 1/20
80 x 70 = 5600 square feet total
5600 / 400 = 14
