Math Problem Statement

You spend 2 1/2 hours on homework on Tuesday. On Wednesday, you spend 1 2/3 hours on homework. Find the total amount of time you spend doing homework on Tuesday and Wednesday.

Solution

The problem asks to find the total time spent on homework over Tuesday and Wednesday. Let's break it down:

  • On Tuesday, you spend 2122 \frac{1}{2} hours on homework.
  • On Wednesday, you spend 1231 \frac{2}{3} hours on homework.

We need to add these two mixed numbers together.

Step 1: Convert the mixed numbers to improper fractions.

  • 212=522 \frac{1}{2} = \frac{5}{2}
  • 123=531 \frac{2}{3} = \frac{5}{3}

Step 2: Find a common denominator for the fractions.

The denominators are 2 and 3. The least common denominator (LCD) is 6.

  • Convert 52\frac{5}{2} to an equivalent fraction with a denominator of 6: 52=156\frac{5}{2} = \frac{15}{6}

  • Convert 53\frac{5}{3} to an equivalent fraction with a denominator of 6: 53=106\frac{5}{3} = \frac{10}{6}

Step 3: Add the two fractions.

156+106=256\frac{15}{6} + \frac{10}{6} = \frac{25}{6}

Step 4: Convert the improper fraction back to a mixed number.

256=416\frac{25}{6} = 4 \frac{1}{6}

Conclusion:

The total time spent on homework on Tuesday and Wednesday is 4 hours and 10 minutes (since 16\frac{1}{6} of an hour is 10 minutes).
