Which of the following statement is true?
l. $\frac{1}{2}+\frac{1}{6}+\frac{1}{12}=\frac{3}{4}$
ll. $\frac{1}{6}+\frac{1}{12}+\frac{1}{20}=\frac{3}{5}$
Answer & explanation
Correct answer: option 3
l. $\frac{1}{2}+\frac{1}{6}+\frac{1}{12}=\frac{3}{4}$
= \(\frac{6 + 2 + 1}{12}\) = \(\frac{3}{4}\) (True)
ll. $\frac{1}{6}+\frac{1}{12}+\frac{1}{20}=\frac{3}{5}$
= \(\frac{10 + 5 + 3}{60}\) = \(\frac{3}{10}\) ( False)
Only I is correct.
