Zorluk: OrtaFractions, Decimals, and Percentages

Four numerical values are given below. Arrange these values in order from least to greatest.

  1. 155%55\%
  2. 20.5650.565
  3. 347\frac{4}{7}
  4. 435\frac{3}{5}

Cevap

The correct order from least to greatest is 55%55\%, 0.5650.565, 47\frac{4}{7}, and 35\frac{3}{5}.
Converting each quantity into a decimal format yields 55%=0.5555\% = 0.55, 0.565=0.5650.565 = 0.565, 470.5714\frac{4}{7} \approx 0.5714, and 35=0.60\frac{3}{5} = 0.60. Ordering these decimal values from least to greatest yields 0.55<0.565<0.5714<0.600.55 < 0.565 < 0.5714 < 0.60, which corresponds to the sequence 55%,0.565,47,3555\%, 0.565, \frac{4}{7}, \frac{3}{5}.

Adım Adım Çözüm

1
Convert the percentage to a decimal.
55%=55100=0.5555\% = \frac{55}{100} = 0.55
Converting all values to decimals provides a uniform scale for direct comparison.
2
Convert the fractions to decimals.
470.5714\frac{4}{7} \approx 0.5714 and 35=0.60\frac{3}{5} = 0.60
Dividing the numerator by the denominator converts each fraction into decimal form.
3
Compare all four decimal values: 0.550.55, 0.5650.565, 0.57140.5714, and 0.600.60.
0.55<0.565<0.5714<0.600.55 < 0.565 < 0.5714 < 0.60
Aligning decimal places shows that 0.5500<0.5650<0.5714<0.60000.5500 < 0.5650 < 0.5714 < 0.6000.
4
Map the ordered decimal values back to their original forms.
55%<0.565<47<3555\% < 0.565 < \frac{4}{7} < \frac{3}{5}
Replacing each decimal with its original representation produces the required sequence.
