Question

Wanda spent 4 1/8 hours studying last night. She spent 1/3 of the time studying math. How much time did she spend studying math?

Answer 1

Answer:

$1\frac{3}{8}$ hours, or 1 hour and 22.5 minutes

Step-by-step explanation:

Wanda spends a third of her $4\frac{1}{8}$ hours studying math. Let us multiply these two fractions to find how much time she spent. Our first step would be to convert the mixed number into an improper fraction, as mixed numbers are hard to manipulate with:

$4\frac{1}{8} =\\\frac{33}{8}$

Now let us multiply:

$\frac{1}{3} *\frac{33}{8} =\\\frac{11}{8}$

If we wish, we can convert this into a mixed number:

$\frac{11}{8}= \\1\frac{3}{8}$

or, 1 hour and 22.5 minutes.

Therefore, Wanda spent $1\frac{3}{8}$ hours, or 1 hour and 22.5 minutes studying math.

I hope this helps! Let me know if you have any questions :)
