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 $\frac{1}{16}$

Maslowich

To find the number of boxes divide the total kids by number of pencils in each box. Here 105/12 leaves remainder. It means still kids are left over. So add 1 to the quotient
105/12= 8 and remainder is 9.
So add 1 to the quotient 8 which is 9
Total pencil boxes = 9
