Question

How many 1/4 fit in 1/8

Answer 1

A restatement of the question would be: what is (1/8) divided by (1/4)?

Dividing by a fraction is the same as multiplying by the fraction's reciprocal. To find the reciprocal of a fraction, flip the numerator and denominator. The reciprocal of (1/4) is 4/1 = 4. 
Remember when multiplying fractions, multiply numerators with numerators and denominators with denominators.
$\frac{1}{8}/ \frac{1}{4} = \frac{1}{8}* \frac{4}{1}= \frac{1}{2}$

Another way to think of this is as an equation.
Let x be how many times (1/4) can fit into (1/8)
$\frac{1}{4}x= \frac{1}{8} \\ x = \frac{1}{8}/ \frac{1}{4} = \frac{1}{8}*4= \frac{1}{2}$

Answer 2

1/4 is equivalent to .25. and 1/8 is .125. so only half of 1/4 fits in 1/8.
