Full solution

Q. Solve for u u .\newlineu34=835u-\frac{3}{4}=8 \frac{3}{5}
  1. Convert to Improper Fraction: Convert the mixed number 8(35)8\left(\frac{3}{5}\right) to an improper fraction.\newlineTo convert a mixed number to an improper fraction, multiply the whole number by the denominator of the fraction and add the numerator. Then place the result over the original denominator.\newline8(35)=(8×5+3)/58\left(\frac{3}{5}\right) = \left(8 \times 5 + 3\right) / 5\newline8(35)=(40+3)/58\left(\frac{3}{5}\right) = \left(40 + 3\right) / 5\newline8(35)=43/58\left(\frac{3}{5}\right) = 43/5
  2. Replace with Improper Fraction: Rewrite the equation with the improper fraction.\newlineReplace the mixed number in the equation with the improper fraction.\newlineu34=435u - \frac{3}{4} = \frac{43}{5}
  3. Find Common Denominator: Find a common denominator to combine the fractions.\newlineThe common denominator for 44 and 55 is 2020. Convert each fraction to an equivalent fraction with a denominator of 2020.\newline(34)=(3×54×5)=1520(\frac{3}{4}) = (\frac{3 \times 5}{4 \times 5}) = \frac{15}{20}\newline(435)=(43×45×4)=17220(\frac{43}{5}) = (\frac{43 \times 4}{5 \times 4}) = \frac{172}{20}\newlineNow the equation is:\newlineu1520=17220u - \frac{15}{20} = \frac{172}{20}
  4. Add to Isolate u: Add 1520\frac{15}{20} to both sides to isolate uu. \newlineu1520+1520=17220+1520u - \frac{15}{20} + \frac{15}{20} = \frac{172}{20} + \frac{15}{20}\newlineu=17220+1520u = \frac{172}{20} + \frac{15}{20}
  5. Combine Fractions: Combine the fractions on the right side of the equation.\newlineAdd the numerators and keep the denominator the same.\newlineu=172+1520u = \frac{172 + 15}{20}\newlineu=18720u = \frac{187}{20}
  6. Convert to Mixed Number: Convert the improper fraction back to a mixed number if necessary.\newlineTo convert an improper fraction to a mixed number, divide the numerator by the denominator.\newline18720=9\frac{187}{20} = 9 with a remainder of 77\newlineSo, 18720=9(720)\frac{187}{20} = 9\left(\frac{7}{20}\right)
