Zorluk: OrtaFractions, Decimals, and Percentages

Four real estate agents reported the proportion of their home listings that sold above asking price last month as follows: Agent W reported 3150\frac{31}{50}, Agent X reported 58\frac{5}{8}, Agent Y reported 63%63\%, and Agent Z reported 0.640.64. Place the four agents in order from the smallest proportion of listings sold above asking price to the largest proportion.

  1. 1Agent W: 3150\frac{31}{50}
  2. 2Agent X: 58\frac{5}{8}
  3. 3Agent Y: 63%63\%
  4. 4Agent Z: 0.640.64

Cevap

The correct order from smallest to largest proportion is Agent W (31/50 = 0.62), Agent X (5/8 = 0.625), Agent Y (63% = 0.63), and Agent Z (0.64).
To place the values in ascending order, convert all values to decimals: Agent W = 31/50 = 0.620, Agent X = 5/8 = 0.625, Agent Y = 63% = 0.630, and Agent Z = 0.640. Arranging these from least to greatest gives 0.620 < 0.625 < 0.630 < 0.640, corresponding to the sequence Agent W, Agent X, Agent Y, and Agent Z.

Adım Adım Çözüm

1
Convert each fraction, percentage, and decimal to a common decimal representation to facilitate comparison.
All four numbers will be expressed as decimals rounded/extended to three decimal places.
Converting all values to decimals makes comparing their magnitudes straightforward.
2
Convert Agent W's value: 3150\frac{31}{50}.
3150=62100=0.620\frac{31}{50} = \frac{62}{100} = 0.620
Multiply numerator and denominator by 2 to convert to hundreds.
3
Convert Agent X's value: 58\frac{5}{8}.
58=5÷8=0.625\frac{5}{8} = 5 \div 8 = 0.625
Perform long division of 5 by 8.
4
Convert Agent Y's value: 63%63\%.
63%=63100=0.63063\% = \frac{63}{100} = 0.630
Divide percentage value by 100 to obtain decimal format.
5
Note Agent Z's value, which is already a decimal.
0.64=0.6400.64 = 0.640
Align decimal places with the other converted values.
6
Order the decimal values from smallest to largest.
0.620<0.625<0.630<0.6400.620 < 0.625 < 0.630 < 0.640, which corresponds to Agent W, Agent X, Agent Y, and Agent Z.
Comparing digits from left to right establishes the proper sequence.
