7 copies of the sum of 8 fifths and 4<\/p>\n\n\n\n

The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n

Let’s break down the problem step-by-step:<\/p>\n\n\n\n

Problem:<\/strong>
“7 copies of the sum of 8 fifths and 4”<\/p>\n\n\n\n

\n\n\n\n

Step 1: Understand the phrase<\/h3>\n\n\n\n
    \n
  • “8 fifths” means the fraction 85\\frac{8}{5}.<\/li>\n\n\n\n
  • “Sum of 8 fifths and 4” means 85+4\\frac{8}{5} + 4.<\/li>\n\n\n\n
  • “7 copies of” means multiply the sum by 7.<\/li>\n<\/ul>\n\n\n\n

    So, mathematically, the expression is:
    7\u00d7(85+4)7 \\times \\left(\\frac{8}{5} + 4\\right)<\/p>\n\n\n\n

    \n\n\n\n

    Step 2: Calculate the sum inside the parentheses<\/h3>\n\n\n\n

    Convert the whole number 4 to a fraction with denominator 5 to add easily:
    4=4\u00d755=2054 = \\frac{4 \\times 5}{5} = \\frac{20}{5}<\/p>\n\n\n\n

    Now add: 85+205=8+205=285\\frac{8}{5} + \\frac{20}{5} = \\frac{8 + 20}{5} = \\frac{28}{5}<\/p>\n\n\n\n

    \n\n\n\n

    Step 3: Multiply by 7<\/h3>\n\n\n\n

    Multiply 285\\frac{28}{5} by 7: 7\u00d7285=7\u00d7285=19657 \\times \\frac{28}{5} = \\frac{7 \\times 28}{5} = \\frac{196}{5}<\/p>\n\n\n\n

    \n\n\n\n

    Step 4: Simplify or convert to mixed number<\/h3>\n\n\n\n

    Divide 196 by 5: 196\u00f75=39 remainder 1196 \\div 5 = 39 \\text{ remainder } 1<\/p>\n\n\n\n

    So, 1965=3915\\frac{196}{5} = 39 \\frac{1}{5}<\/p>\n\n\n\n

    \n\n\n\n

    Final answer:<\/strong><\/h3>\n\n\n\n

    7\u00d7(85+4)=1965=39157 \\times \\left(\\frac{8}{5} + 4\\right) = \\frac{196}{5} = 39 \\frac{1}{5}<\/p>\n\n\n\n

    \n\n\n\n

    Explanation (300 words):<\/h2>\n\n\n\n

    This problem involves basic operations with fractions and whole numbers. First, it’s important to understand the phrase \u201c7 copies of the sum of 8 fifths and 4.\u201d “Copies” means multiplication. So, 7 copies mean multiplying by 7. The “sum of 8 fifths and 4” means adding the fraction 85\\frac{8}{5} to the whole number 4.<\/p>\n\n\n\n

    Because fractions and whole numbers must have a common form to be added, the whole number 4 can be expressed as 205\\frac{20}{5} (since 4=2054 = \\frac{20}{5}). This allows for straightforward addition of fractions with a common denominator: 85+205=285\\frac{8}{5} + \\frac{20}{5} = \\frac{28}{5}<\/p>\n\n\n\n

    Next, multiplying the sum 285\\frac{28}{5} by 7 involves multiplying the numerator by 7 while keeping the denominator the same: 7\u00d7285=19657 \\times \\frac{28}{5} = \\frac{196}{5}<\/p>\n\n\n\n

    Finally, this improper fraction 1965\\frac{196}{5} can be converted to a mixed number by dividing the numerator by the denominator: 196\u00f75=39 remainder 1196 \\div 5 = 39 \\text{ remainder } 1<\/p>\n\n\n\n

    So, the mixed number is 391539 \\frac{1}{5}. This mixed number shows that seven copies of the sum equal thirty-nine wholes and one-fifth more.<\/p>\n\n\n\n

    In conclusion, the answer is 1965\\frac{196}{5} or 391539 \\frac{1}{5}. Understanding how to convert between whole numbers and fractions and knowing basic fraction addition and multiplication are key to solving this type of problem.<\/p>\n","protected":false},"excerpt":{"rendered":"
