Step-by-step solution for: Decimals, fractions and percentages - Fraction and Decimal ...
Here is the step-by-step solution to complete your worksheet.
To fill in the table, we need to convert between decimals, fractions, and percentages.
* Decimal to Fraction: Write the decimal over 100 (e.g., $0.05 = \frac{5}{100}$) and simplify if possible.
* Decimal to Percentage: Multiply by 100 and add the % sign (move the decimal point two places to the right).
* Fraction to Decimal: Divide the top number by the bottom number. Since these are all over 100, just move the decimal point two places to the left.
* Percentage to Decimal: Divide by 100 (move the decimal point two places to the left).
Row 1: 0.05
* Fraction: $\frac{5}{100}$. Simplify by dividing top and bottom by 5: $\frac{1}{20}$.
* Percentage: $0.05 \times 100 = 5\%$
Row 2: 0.32
* Fraction: $\frac{32}{100}$. Simplify by dividing top and bottom by 4: $\frac{8}{25}$.
* Percentage: $0.32 \times 100 = 32\%$
Row 3: $\frac{23}{100}$
* Decimal: Move decimal 2 places left: $0.23$
* Percentage: The denominator is 100, so it is $23\%$
Row 4: $\frac{7}{100}$
* Decimal: Move decimal 2 places left: $0.07$
* Percentage: The denominator is 100, so it is $7\%$
Row 5: 41%
* Decimal: Move decimal 2 places left: $0.41$
* Fraction: $\frac{41}{100}$ (This cannot be simplified further because 41 is a prime number).
Row 6: 8%
* Decimal: Move decimal 2 places left: $0.08$
* Fraction: $\frac{8}{100}$. Simplify by dividing top and bottom by 4: $\frac{2}{25}$.

To compare these easily, let's convert everything to decimals first.
Set 1: $\frac{7}{100}$, $12\%$, $0.09$
* $\frac{7}{100} = 0.07$
* $12\% = 0.12$
* $0.09 = 0.09$
* Order: $0.07 < 0.09 < 0.12$
* Answer: $\frac{7}{100}, \quad 0.09, \quad 12\%$
Set 2: $\frac{23}{100}$, $3\%$, $0.3$
* $\frac{23}{100} = 0.23$
* $3\% = 0.03$
* $0.3 = 0.30$
* Order: $0.03 < 0.23 < 0.30$
* Answer: $3\%, \quad \frac{23}{100}, \quad 0.3$
Set 3: $\frac{9}{100}$, $10\%$, $0.01$
* $\frac{9}{100} = 0.09$
* $10\% = 0.10$
* $0.01 = 0.01$
* Order: $0.01 < 0.09 < 0.10$
* Answer: $0.01, \quad \frac{9}{100}, \quad 10\%$
