Q. Katya is making a rectangular table that is 34 m \frac{3}{4} \mathrm{~m} wide. The table has an area of 115 m2 1 \frac{1}{5} \mathrm{~m}^{2} \newlineHow long is the table?\newlinem \mathrm{m}
  1. Calculate Area: To find the length of the table, we need to divide the area of the table by its width. Area of the table = 15m2\frac{1}{5}m^2, which can be converted to an improper fraction: 5×1+15=65m2\frac{5\times1 + 1}{5} = \frac{6}{5} m^2. Width of the table = 34m\frac{3}{4}m. Length of the table = Area / Width.
  2. Convert to Improper Fraction: First, let's convert the mixed number for the area into an improper fraction.\newline1151\frac{1}{5} = (5×1+1)5\frac{(5\times1 + 1)}{5} = 65\frac{6}{5} m2m^2.\newlineNow we have the area as an improper fraction, which is easier to work with.
  3. Perform Division: Next, we perform the division to find the length.\newlineLength = AreaWidth=(6/5)m2(3/4)m\frac{\text{Area}}{\text{Width}} = \frac{(6/5)m^2}{(3/4)m}.\newlineTo divide by a fraction, we multiply by its reciprocal.\newlineLength = (6/5)m2×(4/3)m1(6/5)m^2 \times (4/3)m^{-1}.
  4. Multiply Numerators and Denominators: Now, we multiply the numerators and the denominators.\newlineLength = (6×4)/(5×3)(6\times4)/(5\times3) m.\newlineLength = 24/1524/15 m.
  5. Simplify Fraction: We simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 33. \newlineLength = (24/3)/(15/3)m(24/3)/(15/3) \, \text{m}. \newlineLength = 8/5m8/5 \, \text{m}.
  6. Convert Back to Mixed Number: Convert the improper fraction back to a mixed number if necessary.\newlineHowever, in this case, the fraction 85\frac{8}{5} is a simple form and can be left as is.
