How many feet are in 2 3/4 miles? (Hint: 1 mile=5280 feet)
How do I write a proportion to solve this problem.
Please help, thank you.
( 2 3/4 miles ) / ( X feet) =
( 1 mile)/ ( 5280 feet )
then cross multiply
(2 3/4 mi)*(5280 feet)= (x feet)(1 mi)
(2 3/4 )(5280) = x feet
that equals your total feet for 2 3/4 miles.
I DON'T KNOW.THAT'S WHY I AM ASKING YOU GUYS!!!!!!!!!!!!!
Let x = the number of feet in 2 3/4 (2.75) miles. Solve for x.
1 / 5280 as 2.75 / x
meeping noises
bruh
To solve this problem, you can set up a proportion using the given information. A proportion is an equation that states that two ratios are equal.
In this case, we can set up the following proportion:
x/1 = 2 3/4 miles/1 mile
The numerator x represents the number of feet we want to find, and the denominator 1 represents the number of miles. The ratio on the right side of the equation represents the given information, where 2 3/4 miles is equivalent to 1 mile.
Now, to solve for x (the number of feet), we need to cross-multiply and solve for x.
x = (2 3/4 miles) * (5280 feet/1 mile)
First, convert the mixed number 2 3/4 to an improper fraction:
2 3/4 = (2 * 4 + 3) / 4 = 11/4
Now, substitute the value into the proportion:
x = (11/4 miles) * (5280 feet/1 mile)
Next, simplify the expression:
x = (11 * 5280) feet / 4
x = 58080 feet / 4
Finally, divide 58080 feet by 4:
x = 14520 feet
Therefore, there are 14520 feet in 2 3/4 miles.
