Jariah walks 2 1/2 miles in 3/4 of an hour. If Jariah continues at this rate, how far will she walk in 1 hour?
You need to divide 3/4of an hour by 3/4 to find 1 hour. To keep the ratio the same, you also need to divide 2 1/2 miles by 3/4. Start by writing 2 1/4 divided by 3/4 as a multiplication expression.
To find how far Jariah will walk in 1 hour, you need to divide 2 1/2 miles by 3/4.
2 1/2 ÷ 3/4
To divide by a fraction, you can multiply by its reciprocal:
2 1/2 x 4/3
Convert 2 1/2 to an improper fraction:
5/2 x 4/3
Now, multiply the numerators and denominators:
(5 x 4) / (2 x 3) = 20/6
Simplify the fraction:
20/6 = 10/3
Therefore, Jariah will walk 10/3 miles in 1 hour.
