234+253232 \frac{3}{4} + \frac{2}{5} - 3 \frac{2}{3}

Let me solve it for you step-by### Step-by-step Solution:

We are solving:

234+253232 \frac{3}{4} + \frac{2}{5} - 3 \frac{2}{3}

Step 1: Convert mixed fractions to improper fractions

  • 234=84+34=1142 \frac{3}{4} = \frac{8}{4} + \frac{3}{4} = \frac{11}{4}
  • 323=93+23=1133 \frac{2}{3} = \frac{9}{3} + \frac{2}{3} = \frac{11}{3}

So, the expression becomes: 114+25113\frac{11}{4} + \frac{2}{5} - \frac{11}{3}

Step 2: Find the Least Common Denominator (LCD)

The denominators are 4,5,34, 5, 3. The LCD is 6060.

Step 3: Rewrite each fraction with a denominator of 6060

  • 114=11×154×15=16560\frac{11}{4} = \frac{11 \times 15}{4 \times 15} = \frac{165}{60}
  • 25=2×125×12=2460\frac{2}{5} = \frac{2 \times 12}{5 \times 12} = \frac{24}{60}
  • 113=11×203×20=22060\frac{11}{3} = \frac{11 \times 20}{3 \times 20} = \frac{220}{60}

The expression now becomes: 16560+246022060\frac{165}{60} + \frac{24}{60} - \frac{220}{60}

Step 4: Combine the fractions

165+2422060=3160\frac{165 + 24 - 220}{60} = \frac{-31}{60}

Final Answer:

3160- \frac{31}{60}
