  • Therefore, 70% can be written as the decimal 0.7.

Establishing the Relationship

  1. Percentage, Fraction, and Decimal Equivalence:
  • The percentage, fraction, and decimal representations of a value are equivalent.
  • In this case, 70% = 70/100 = 0.7.

Solving for the Unknown Number

  1. Setting up the Equation:
  • Let “x” be the unknown number that 140 represents 70% of.

  • We can set up the following equation:

    140 = (70/100) * x

  1. Isolating the Variable:
  • Multiply both sides of the equation by 100 to get rid of the fraction:

    140 * 100 = (70/100) * x * 100

  • This simplifies to:

    14000 = 70 * x

  1. Solving for “x”:
  • Divide both sides of the equation by 70 to isolate “x”:

    x = 14000 / 70

  • Calculating the value of “x”:

    x = 200

Conclusion

Therefore, 140 is 70% of 200. This demonstrates the interconnectedness of percentages, fractions, and decimals and their significance in solving mathematical problems involving proportional relationships.
