OpenStudy (kayders1997):

You can multiply by the reciprocal when diving you keep the first the same and flip the second number than you can multiply

the choices are

if you solve it that's what you get^^

OpenStudy (anonymous):

1/5 divided by 1/3

OpenStudy (anonymous):

1/5+3

OpenStudy (anonymous):

1/5+1/3

OpenStudy (anonymous):

1/5 times 1/3

OpenStudy (kayders1997):

Pretend you have 3/1 flip that fraction because it is the second fraction diving fractions don't ask when flip the secon number and multiply

OpenStudy (jdoe0001):

any number, any whatsoever, can be written as "over 1" thus 3 is really 3/1 thus \(\bf \cfrac{\frac{1}{5}}{3}\iff \cfrac{\frac{1}{5}}{\frac{3}{1}}\implies \cfrac{1}{5}\cdot \cfrac{1}{3}\implies \cfrac{1}{15}\)

OpenStudy (kayders1997):

Keep first number the same the same so you will have 1/5 flip second fraction 3/1 to 1/3 than multiply so 1/5 times 1/3

OpenStudy (jdoe0001):

and recall that \(\large \cfrac{\frac{a}{b}}{\frac{c}{{\color{blue}{ d}}}}\implies \cfrac{a}{b}\cdot \cfrac{{\color{blue}{ d}}}{c}\)
