country	fraction of population using cell phones	equivalent fraction with a denominator of 100
country b	$\frac{9}{10}$
country c	$\frac{23}{25}$

Explanation:

Step1: For Country A

The fraction $\frac{87}{100}$ already has a denominator of 100, so it remains the same.
$\frac{87}{100}$

Step2: For Country B

To get a denominator of 100 from $\frac{9}{10}$, multiply both numerator and denominator by 10.
$\frac{9\times10}{10\times10}=\frac{90}{100}$

Step3: For Country C

To get a denominator of 100 from $\frac{23}{25}$, multiply both numerator and denominator by 4.
$\frac{23\times4}{25\times4}=\frac{92}{100}$

Answer:

Country A: $\frac{87}{100}$
Country B: $\frac{90}{100}$
Country C: $\frac{92}{100}$
