Question

Find the mean of 1/3,5/7,7/7,9/10,3/4?

Answer 1

Answer:

$\frac{1553}{2100}$

Step-by-step explanation:

Add all data.

→ $(\frac{1}{3} +\frac{5}{7} )+1+(\frac{9}{10} +\frac{3}{4})$

→ $(\frac{7}{21} +\frac{15}{21} )+1+(\frac{18}{20} +\frac{15}{20} )$

→ $\frac{22}{21} +1+\frac{33}{20}$

→ $\frac{440}{420} +1+\frac{693}{420}$

→ $\frac{1133}{420} +1$

→ $\frac{1553}{420}$

Since there are five data : Divide the sum by 5.

→ $\frac{1553}{420} \div 5$

→ $\frac{1553}{2100}$

The answer is $\frac{1553}{2100}$.
