Find the mean (average) of the data set below? 2/4, 18/5, 28/10, 5/20
laila [671]

the mean (average) of the data set below

2/4, 18/5, 28/10, 5/20

We are given with 4 fraction

to find mean , we add all the fractions and divide by 4

Lets add all the fractions

\frac{2}{4} + \frac{18}{5} + \frac{28}{10} + \frac{5}{20}

Make the denominators same

LCM is 20

Try to get 20 in the denominator

\frac{2*5}{4*5} + \frac{18*4}{5*4} + \frac{28*2}{10*2} + \frac{5}{20}

\frac{10}{20} + \frac{72}{20} + \frac{56}{20} + \frac{5}{20}

\frac{143}{20}

Now we divide by 4

\frac{\frac{143}{20}}{4}=\frac{143}{80}=1\frac{63}{80}
