Answer 1

❄️ Proper question :

• Find the average of 4.2, 3.8 and 7.6

❄️ Solution :

$\\ \sf \: Average \: = \: \dfrac{4.2 + 3.8 + 7.6}{3} \\ \\ \sf\implies \: \frac{1}{3} \times (4.2 + 3.8 + 7.6) \\ \\ \sf\implies \: \frac{1}{3} \times ( \frac{42}{10} \times \frac{38}{10} \times \frac{76}{10} ) \\ \\ \sf\implies \: \frac{1}{3} \times ( \frac{42 + 38 + 76}{10} ) \\ \\ \sf\implies \: \frac{1}{3} \times \frac{156}{10} \\ \\ \sf\implies \: \frac{156}{3} \times \frac{1}{10} \\ \\ \sf\implies \: 52 \times \frac{1}{10} \\ \\ \sf\implies \: \frac{52}{10} \\ \\ \sf\implies \: 5.2 \\ \\ \large {\underline{ \boxed{ \purple{\bf \: Average = 5.2 } }}}$
