B is the answer i believe.
Hello there!
By converting 7,200 yards into miles, 7,200 yards would be 4 miles.
But to really give you the correct answer, it would actually be 4.(090909). This extra part would basically almost be known as 1.
So, it would be 4.1 miles.
I hope this helps you!
10^2 = 10 × 10
10^3 = 10 × 10 × 10 = 1000
10^4 = 10 × 10 × 10 × 10
The amount of decrease is (80 - 64) = 16
The fraction of decrease is the fraction of the original amount that disappeared.
That fraction is (16 / 80) = 1/5 = 0.2
To change a decimal to a percent,
move the decimal point 2 places that way ==> .
0.2 = 20%
Then it would be 9/10 don't you know anything times 1 is its self even fractions
