Q. Some friends are planning to make a neighborhood garden. The total area available for the garden is 210square meters210 \, \text{square meters}, and they want this to be 1131 \frac{1}{3} times the area of the plant beds in the garden. What should the area of the plant beds be?
  1. Understand Relationship: Understand the relationship between the total area and the area of the plant beds.\newlineThe total area of the garden is 1131\frac{1}{3} times the area of the plant beds. This means that if we let the area of the plant beds be xx square meters, then the total area is (43)x(\frac{4}{3})x square meters.
  2. Set Up Equation: Set up the equation to find the area of the plant beds.\newlineWe know that the total area is 210210 square meters, so we can set up the equation (43)x=210(\frac{4}{3})x = 210.
  3. Solve for x: Solve for x by multiplying both sides of the equation by the reciprocal of 43\frac{4}{3}.\newlineTo isolate x, we multiply both sides by 34\frac{3}{4}, which is the reciprocal of 43\frac{4}{3}.\newline(34)×(43)x=(34)×210\left(\frac{3}{4}\right) \times \left(\frac{4}{3}\right)x = \left(\frac{3}{4}\right) \times 210
  4. Perform Multiplication: Perform the multiplication to solve for xx.(34)×(43)x=x(\frac{3}{4}) \times (\frac{4}{3})x = x(34)×210=157.5(\frac{3}{4}) \times 210 = 157.5So, x=157.5x = 157.5 square meters.
  5. Check Result: Check the result.\newlineTo check, we can multiply the area of the plant beds by 1131 \frac{1}{3} to see if we get the total area of the garden.\newline113×157.5=(43)×157.5=2101 \frac{1}{3} \times 157.5 = \left(\frac{4}{3}\right) \times 157.5 = 210\newlineThis confirms that our solution is correct.
