Answer:

121/14 or 8 9/14

Step-by-step explanation:

The quotient of 1/8 and 1/4 is ...

(1/8)/(1/4) = (1/8)(4/1) = 4/8 = 1/2

The product of 2 2/3 and 3 3/7 is ...

(2 2/3)(3 3/7) = (8/3)(24/7) = (8·24)/(3·7) = 64/7

Subtracting the first result from the second gives ...

64/7 -1/2 = (128 -7)/14 = 121/14 = 8 9/14

_____

Additional comment

When subtracting fractions with denominators that have no common factors, I find it useful to make use of the formula ...

$\dfrac{a}{b}-\dfrac{c}{d}=\dfrac{ad-bc}{bd}$

In this case, that gives us (64·2 -7·1)/(7·2) = (128 -7)/14.
