Solve the Mixed Number Equation: 5⅔ + ? = 6⅗

Question

527+?=637 5\frac{2}{7}+?=6\frac{3}{7}

Video Solution

Step-by-Step Solution

To solve the given equation 527+?=637 5\frac{2}{7} + ? = 6\frac{3}{7} , follow these steps:

  • Step 1: Convert mixed numbers into improper fractions to clarify the calculation.
  • The mixed number 5275\frac{2}{7} is converted as follows:
    The improper fraction becomes 57+2=3775 \cdot 7 + 2 = \frac{37}{7}.

    The mixed number 6376\frac{3}{7} is converted as follows:
    The improper fraction becomes 67+3=4576 \cdot 7 + 3 = \frac{45}{7}.

  • Step 2: Calculate the difference to find the missing number.
  • Since we need to find what 6376\frac{3}{7} is when 5275\frac{2}{7} is added to it, determine the difference:
    Subtract the fraction 377\frac{37}{7} from 457\frac{45}{7}:
    457377=87\frac{45}{7} - \frac{37}{7} = \frac{8}{7}.

  • Step 3: Convert the resulting improper fraction back to a mixed number.
  • The fraction 87\frac{8}{7} can be converted to the mixed number 1171\frac{1}{7}. This involves dividing 8 by 7, which yields a quotient of 1 with a remainder of 1.

Thus, the missing number is indeed 1171\frac{1}{7}.

The correct choice among the options provided is: 117 1\frac{1}{7}

Answer

117 1\frac{1}{7}
