667414= 6 \frac{6}{7}-4 \frac{1}{4}=

Full solution

Q. 667414= 6 \frac{6}{7}-4 \frac{1}{4}=
  1. Understand the problem: Understand the problem.\newlineWe need to subtract the fraction 4144\frac{1}{4} from the fraction 6676\frac{6}{7}.
  2. Convert to improper fractions: Convert the mixed numbers to improper fractions.\newline6676\frac{6}{7} can be converted to an improper fraction by multiplying the whole number 66 by the denominator 77 and adding the numerator 66, then placing the result over the original denominator.\newline667=6×7+67=42+67=4876\frac{6}{7} = \frac{6\times7 + 6}{7} = \frac{42 + 6}{7} = \frac{48}{7}\newlineSimilarly, for 4144\frac{1}{4}, multiply the whole number 44 by the denominator 44 and add the numerator 11, then place the result over the original denominator.\newline414=4×4+14=16+14=1744\frac{1}{4} = \frac{4\times4 + 1}{4} = \frac{16 + 1}{4} = \frac{17}{4}
  3. Find common denominator: Subtract the second fraction from the first.\newlineNow we have two improper fractions: 487\frac{48}{7} and 174\frac{17}{4}. To subtract them, we need a common denominator. The least common multiple (LCM) of 77 and 44 is 2828.
  4. Convert to common denominator: Convert both fractions to have the common denominator of 2828. For 487\frac{48}{7}, we multiply both the numerator and the denominator by 44 to get the equivalent fraction with a denominator of 2828. 487×44=48×47×4=19228\frac{48}{7} \times \frac{4}{4} = \frac{48\times4}{7\times4} = \frac{192}{28} For 174\frac{17}{4}, we multiply both the numerator and the denominator by 77 to get the equivalent fraction with a denominator of 2828. 174×77=17×74×7=11928\frac{17}{4} \times \frac{7}{7} = \frac{17\times7}{4\times7} = \frac{119}{28}
  5. Subtract with common denominator: Subtract the fractions with the common denominator.\newlineNow we subtract 11928\frac{119}{28} from 19228\frac{192}{28}.\newline1922811928=19211928=7328\frac{192}{28} - \frac{119}{28} = \frac{192 - 119}{28} = \frac{73}{28}
  6. Simplify result: Simplify the result, if possible. 7328\frac{73}{28} cannot be simplified further as 7373 is a prime number and does not share any common factors with 2828.
