Answer:

x=3

Step-by-step explanation:

6 10

---------- = ------------

6+x 15

using cross products

6 * 15 = 10 * (6+x)

90 = 60+10x

subtract 60 from each side

90-60 = 60+10x-60

30 = 10x

divide by 10

30/10 = 10x/10

3=x

Greg’s house is 0.8 miles from the library. So far, Greg has walked 5/6 of the distance. How many miles has he walked in fractio

Anastaziya [24]

Greg has walked $\frac{2}{3}$ miles

<em><u>Solution:</u></em>

Given that, Greg’s house is 0.8 miles from the library

Distance between house and library = 0.8 miles

Greg has walked $\frac{5}{6}$ of the distance

Therefore,

Distance walked = $\frac{5}{6}$ of the distance between house and library

Here "of" means multiplication

Thus we get,

$\text{Distance walked } = \frac{5}{6} \text{ of } 0.8$

$\rightarrow \frac{5}{6} \times 0.8 = \frac{5}{6} \times \frac{8}{10}\\\\\text{Simplify the above fraction by reducing to lowest terms }\\\\\rightarrow \frac{5}{6} \times \frac{8}{10}=\frac{2}{3}$

Thus Greg has walked $\frac{2}{3}$ miles
