Question

157:113= 1\frac{5}{7}:1\frac{1}{3}=

Video Solution

Step-by-Step Solution

To solve this division of mixed numbers, follow these detailed steps:

  • Step 1: Convert each mixed number to an improper fraction.
  • Step 2: Divide by multiplying by the reciprocal of the second fraction.
  • Step 3: Simplify the resulting fraction and convert it back to a mixed number, if necessary.

Let's perform each step with the given numbers:

Step 1: Convert the mixed numbers to improper fractions.
157=1×7+57=127 1\frac{5}{7} = \frac{1 \times 7 + 5}{7} = \frac{12}{7}
113=1×3+13=43 1\frac{1}{3} = \frac{1 \times 3 + 1}{3} = \frac{4}{3}

Step 2: Instead of dividing by 43\frac{4}{3}, multiply by its reciprocal, which is 34\frac{3}{4}.
127×34=12×37×4=3628 \frac{12}{7} \times \frac{3}{4} = \frac{12 \times 3}{7 \times 4} = \frac{36}{28}

Step 3: Simplify the fraction 3628\frac{36}{28}.
Both the numerator and the denominator are divisible by 4:
36÷428÷4=97 \frac{36 \div 4}{28 \div 4} = \frac{9}{7}

Convert 97\frac{9}{7} back to a mixed number:
Since 99 divided by 77 is 11 with a remainder of 22, it becomes:
127 1\frac{2}{7}

Therefore, the solution to the problem is 127 1\frac{2}{7} .

Answer

127 1\frac{2}{7}
