<h2>Hello!</h2>

We can solve in just two or three steeps:

\frac{6}{7} x+\frac{1}{2} =\frac{7}{8} \\\\\\\frac{6}{7} x =\frac{7}{8} - \frac{1}{2}\\

There are a lot of ways to sum or difference fractions, but we can solve it using the easiest way.

First, we need to multiply the first fraction numerator by the second fraction denominator

Second, we need to multiply the first fraction denominator by the second fraction numerator

Third, we need to solve the operation depending if it's a sum or a difference

Fourth, we have to multiply the denominator of each fraction and it will be our new fraction denominator

Knowing that we have that

\frac{7}{8} - \frac{1}{2}= \frac{14-8}{16} =\frac{6}{16} =\frac{3}{8}

So,

\frac{6}{7}x= \frac{3}{8}\\\\x=\frac{3}{8} *\frac{7}{6} =\frac{21}{48}= \frac{7}{16}

Have a nice day!

Burka [1]

Answer:

2 1/4 times

Step-by-step explanation:

A builder was building a fence. In the moring he worked 2/5 of an hour. In the afternoon he wirked for 9/10 of an hour. how many times as long in the morning did he work in the afternoon

Note that:

1 hour = 60 minutes

In the moring he worked 2/5 of an hour.

= 2/5 × 60 minutes

= 24 minutes

In the afternoon he worked for 9/10 of an hour

Hence:

9/10 × 60 minutes

= 54 minutes

How many times as long in the morning did he work in the afternoon?

This is calculated as number of minutes worked in the afternoon ÷ Number of minutes worked in the morning

= 54 minutes/24 minutes

= 2 6/24

= 2 1/4 times

80 x 50 = 4,000.

So now, make it division. 

4,000/80 = 50.
