Question

A bathtub is filled with 38 1/3 gallons of water. If 2 3/5 gallons splash out, how much water is left in the tube

Answer 1

So let's convert these to improper fractions:

$38\frac{1}{3}=\frac{115}{3}$

$2\frac{3}{5}=\frac{13}{5}$

Then let's convert these fractions so that they have a denominator of 15 so we can better compare these numbers:

$\frac{115}{3}=\frac{575}{15}$

$\frac{13}{5}=\frac{39}{15}$

So when we have $\frac{39}{15}$ gallons splash out, we are left with $\frac{536}{15}$ gallons or $35\frac{11}{15}$ gallons in the tub.
