Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Convert 4234\frac{2}{3} and 1151\frac{1}{5} to improper fractions.
  • Step 2: Multiply these improper fractions.
  • Step 3: Simplify the result, if necessary, and convert it back to a mixed number.

Now, let's work through each step:
Step 1: Convert mixed numbers to improper fractions:
For 4234\frac{2}{3}:
Multiply the whole number 4 by the denominator 3 and add the numerator 2:
4×3+2=12+2=144 \times 3 + 2 = 12 + 2 = 14.
Thus, 423=1434\frac{2}{3} = \frac{14}{3}.
For 1151\frac{1}{5}:
Multiply the whole number 1 by the denominator 5 and add the numerator 1:
1×5+1=5+1=61 \times 5 + 1 = 5 + 1 = 6.
Thus, 115=651\frac{1}{5} = \frac{6}{5}.

Step 2: Multiply the improper fractions 143\frac{14}{3} and 65\frac{6}{5}:
143×65=14×63×5=8415\frac{14}{3} \times \frac{6}{5} = \frac{14 \times 6}{3 \times 5} = \frac{84}{15}.

Step 3: Simplify the resulting fraction 8415\frac{84}{15} and convert it to a mixed number if necessary:
Find the greatest common divisor (GCD) of 84 and 15, which is 3.
Divide both numerator and denominator by their GCD:
84÷315÷3=285\frac{84 \div 3}{15 \div 3} = \frac{28}{5}.

Convert the improper fraction 285\frac{28}{5} to a mixed number:
Divide 28 by 5: Quotient is 5, remainder is 3.
Thus, 285=535\frac{28}{5} = 5\frac{3}{5}.

Therefore, the solution to the problem is 5355\frac{3}{5}.

Answer

535 5\frac{3}{5}
