c. what fraction more of these students write l8r than cul8r when using instant messenger?
instant messenger abbreviations
l8r (later) (\frac{48}{100})
lol (laughing out loud) (\frac{26}{100})
brb (be right back) (\frac{19}{100})
cul8r (see you later) (\frac{7}{100})

Explanation:

Part (a)

Step1: Identify fractions for LOL and CUL8R

Fraction for LOL: $\frac{28}{100}$, Fraction for CUL8R: $\frac{7}{100}$

Step2: Add the two fractions

$\frac{28}{100} + \frac{7}{100} = \frac{28 + 7}{100} = \frac{35}{100} = \frac{7}{20}$ (simplified)

Step1: Identify fractions for L8R and BRB

Fraction for L8R: $\frac{46}{100}$, Fraction for BRB: $\frac{19}{100}$

Step2: Add the two fractions

$\frac{46}{100} + \frac{19}{100} = \frac{46 + 19}{100} = \frac{65}{100} = \frac{13}{20}$ (simplified)

Step1: Identify fractions for L8R and CUL8R

Fraction for L8R: $\frac{46}{100}$, Fraction for CUL8R: $\frac{7}{100}$

Step2: Subtract the fractions

$\frac{46}{100} - \frac{7}{100} = \frac{46 - 7}{100} = \frac{39}{100}$

Answer:

$\frac{7}{20}$ (or $\frac{35}{100}$)
