There are 5280 feet in a mile what factors of a mile is represented by 480 feet
1 answer:
Remark
I take this to mean "What fraction of a mile." Factors and fractions are two different things. If I have made the wrong assumption, please leave a note.
1 mile = 5280 feet
x mile = 480 feet
Discussion
The easiest way to get the fractional amount is to find the Highest Common Factor and cancel it out. What is left will be your answer.
480:2* 2*2*2 *2 * 3 *5
5280:2*2*2*2*2*3*5*11
The bold primes make up the LCM
Answer
is what is left over.
So 480 is 1/11 of 5280 <<< Answer

Answer:
y = 2
Step-by-step explanation:
y varies inversely with x setup is:
y = k/x
7 = (find 'k')
k = 7/1 · 2/3
k = 14/3
use what you know about 'k' and 'x' to solve for 'y'
y = 14/3 ÷ 7/3 (remember to multiply by the reciprocal when dividing fractions)
y = 14/3 · 3/7
y = 2
