To make this easier, we can convert the fractions into decimals. 3/4 is 0.75. 1 and 1/2 would be 1.50 and 2 and 1/4 would be 2.25. Now, let us to the subtraction in order for us to know the difference of each. So 1.50 minus 0.75 would be 0.75. And 2.25 minus 1.50 is also 0.75. 0.75 is 3/4 and this means that she increased 3/4 hour each day.

What is 1/8 divided by 2
slavikrds [6]
When dividing 1/8 by 2
we have to first take the reciprocal of 2 
reciprocal is when the numerator and denominator are exchanged
2 when written as a fraction is \frac{2}{1}
we need to find the reciprocal of \frac{2}{1} which is \frac{1}{2}
then 
\frac{1}{2} of \frac{1}{8}
when 'of' function is used it means to multiply the 2 fractions 
when multiplying fractions multiply the numerators by numerators and multiply denominators by denominators 
is \frac{1}{2} * \frac{1}{8} =  \frac{1}{16}
answer is \frac{1}{16}
