Exercise #1

Write the fraction as a mixed number:

107= \frac{10}{7}=

Video Solution

Step-by-Step Solution

To solve the problem, we will convert the given improper fraction 107\frac{10}{7} to a mixed number by dividing the numerator by the denominator.

  • Step 1: Divide the numerator (10) by the denominator (7). This gives a quotient and a remainder.

  • Step 2: Calculating 10÷710 \div 7 gives a quotient of 1 because 7 goes into 10 once.

  • Step 3: Multiply the quotient by the divisor (1×7=7 1 \times 7 = 7 ).

  • Step 4: Subtract the product obtained in step 3 from the original numerator to find the remainder: 107=310 - 7 = 3.

  • Step 5: Compose the mixed number using the quotient as the whole number and the remainder over the divisor as the fraction part: 37\frac{3}{7}.

Thus, the mixed number representation of 107\frac{10}{7} is 137\mathbf{1\frac{3}{7}}.
