Question

the table shows the fraction of the population in selected countries that used cell phones in a recent year. complete the table by writing each fraction as an equivalent fraction with a denominator of 100.

country	fraction of population using cell phones	equivalent fraction with a denominator of 100
country b	$\frac{9}{10}$	$\frac{90}{100}$
country c	$\frac{23}{25}$	$\frac{92}{100}$
country d	$\frac{23}{25}$	$\frac{92}{100}$
country e	$\frac{16}{25}$	$\frac{64}{100}$
country f	$\frac{93}{100}$

Explanation:

Step1: Analyze the given fractions

We need to convert each fraction to an equivalent fraction with denominator 100.

Step2: For Country B

We have the fraction $\frac{9}{10}$. To get a denominator of 100, we multiply both the numerator and denominator by 10. So, $\frac{9\times10}{10\times10}=\frac{90}{100}$.

Step3: For Country C

We have the fraction $\frac{23}{25}$. To get a denominator of 100, we multiply both the numerator and denominator by 4. So, $\frac{23\times4}{25\times4}=\frac{92}{100}$.

Step4: For Country D

Same as Country C, $\frac{23}{25}=\frac{23\times4}{25\times4}=\frac{92}{100}$.

Step5: For Country E

We have the fraction $\frac{16}{25}$. To get a denominator of 100, we multiply both the numerator and denominator by 4. So, $\frac{16\times4}{25\times4}=\frac{64}{100}$.

Step6: For Country F

The fraction is $\frac{93}{100}$, which already has a denominator of 100.

Answer:

Country	Fraction of Population Using Cell Phones	Equivalent Fraction with a Denominator of 100
Country B	$\frac{9}{10}$	$\frac{90}{100}$
Country C	$\frac{23}{25}$	$\frac{92}{100}$
Country D	$\frac{23}{25}$	$\frac{92}{100}$
Country E	$\frac{16}{25}$	$\frac{64}{100}$
Country F	$\frac{93}{100}$	$\frac{93}{100}$
