Question

Ethan and Rylee hiked 5 13/15 miles. In one day, Gianna hiked 3 3/4 times as far as Ethan and Rylee hike. How far did she hike?

Answer 1

Answer: 22 miles in one day

Step-by-step explanation:

To find how far Gianna hiked, we first need to convert the mixed number for Ethan and Rylee's hike into an improper fraction, and then multiply it by 3 3/4 to find the distance Gianna hiked.

Ethan and Rylee's hike (5 13/15):

(15 * 5) + 13 = 88

So, they hiked 88/15 miles.

Now, let's convert the mixed number 3 3/4 into an improper fraction:

(4 * 3) + 3 = 15

So, 3 3/4 = 15/4.

Next, we'll multiply the two improper fractions together:

(88/15) * (15/4) = (88 * 15) / (15 * 4) = 1320 / 60

Now, simplify the fraction:

1320 ÷ 60 = 22

So, Gianna hiked 22 miles in one day.
