Q. Bjorn is making aush, and he does not have enough of all the ingredients. He decides to make 56 \frac{5}{6} of a whole recipe, which means he uses 114 L 1 \frac{1}{4} \mathrm{~L} of water.\newlineHow much water is in a whole recipe?\newlineL
  1. Convert to Improper Fraction: Bjorn uses 1(14)L1\left(\frac{1}{4}\right)L of water for (56)\left(\frac{5}{6}\right) of the recipe. We need to find out how much water is needed for the whole recipe. We can set up a proportion to solve for the total amount of water needed.
  2. Set Up Proportion: First, we convert the mixed number 1(14)L1\left(\frac{1}{4}\right)L to an improper fraction. 1(14)L1\left(\frac{1}{4}\right)L is the same as (54)L\left(\frac{5}{4}\right)L because 1L1L is the same as (44)L\left(\frac{4}{4}\right)L, and we add (14)L\left(\frac{1}{4}\right)L to it.\newlineCalculation: $\(1\)L + \left(\frac{\(1\)}{\(4\)}\right)L = \left(\frac{\(4\)}{\(4\)}\right)L + \left(\frac{\(1\)}{\(4\)}\right)L = \left(\frac{\(5\)}{\(4\)}\right)L
  3. Cross-Multiply: Now we set up the proportion. If \((\frac{5}{6})\) of the recipe requires \((\frac{5}{4})L\) of water, then the whole recipe (which is \(1\) or \((\frac{6}{6})\) of the recipe) requires \(X\) liters of water.\(\newline\)Proportion: \(\frac{(\frac{5}{6}) \text{ recipe}}{(\frac{5}{4})L} = \frac{(\frac{6}{6}) \text{ recipe}}{X L}\)
  4. Simplify Equation: We can solve for \(X\) by cross-multiplying.\(\frac{5}{6} \times X = \frac{6}{6} \times \frac{5}{4}\)
  5. Divide by Reciprocal: Simplify the equation.\(\newline\)\(X = \left(\frac{6}{6}\right) \times \left(\frac{5}{4}\right) / \left(\frac{5}{6}\right)\)
  6. Cancel Common Factors: Since \((\frac{6}{6})\) is equal to \(1\), the equation simplifies to: \(X = \frac{\frac{5}{4}}{\frac{5}{6}}\)
  7. Multiply Fractions: To divide by a fraction, we multiply by its reciprocal. \(X = \frac{5}{4} \times \frac{6}{5}\)
  8. Simplify Fraction: We can cancel out the common factors of \(5\) in the numerator and denominator.\[X = \left(\frac{1}{4}\right) * \left(\frac{6}{1}\right)\]
  9. Convert to Mixed Number: Now we multiply the remaining fractions. \(X = \frac{6}{4}\)
  10. Convert to Mixed Number: Now we multiply the remaining fractions.\(\newline\)\(X = \frac{6}{4}\)Simplify the fraction \(\frac{6}{4}\) by dividing both the numerator and the denominator by their greatest common divisor, which is \(2\).\(\newline\)\(X = \frac{6}{4} / 2\)\(\newline\)\(X = \frac{3}{2}\)
  11. Convert to Mixed Number: Now we multiply the remaining fractions. \(\newline\)\(X = \frac{6}{4}\) Simplify the fraction \(\frac{6}{4}\) by dividing both the numerator and the denominator by their greatest common divisor, which is \(2\). \(\newline\)\(X = \frac{6}{4} / 2\) \(\newline\)\(X = \frac{3}{2}\) Convert the improper fraction \(\frac{3}{2}\) back to a mixed number to find the total liters of water needed for the whole recipe. \(\newline\)\(X = 1\frac{1}{2}\)L
