2/3 + 1/6 In the numerator position
______________________________________ Fraction Line and then multiply by 1/7
1/5 - 1/10 In the denominator position

The fraction looks like this
2/3 + 1/6
__________________ X (multiply) 1/7
1/5 - 1/10

In the 'large' fraction multiply each of the four 'small' fractions by \(\displaystyle 30\) then combine the four results then multiply by one seventh.

the bottom is incorrect it should be 1/5 - 1/10

Ok so did I do this correctly or did I miss something..
5/6 /1 5/6*1 = 5/6
5/6 / 10 = 5/60
5/60= 1/12

1/12 * 1/7
= 1/84
Is that correct or can I not do it that way

Nooooooo!

I don't know what you are doing.

In response #15 you had:

25/3 * 1/7 which was equal to: \(\displaystyle \frac{\frac{2}{3} \ + \frac{1}{6}}{\frac{1}{5} \ - \frac{1}{10}} \ * \ \frac{1}{7}\)

now:

25/3 * 1/7 converts \(\displaystyle \ \to \ \frac{25 * 1}{3 * 7}\)

can you complete it?
