Question 1
The value of $$999\frac{1}{7}+999\frac{2}{7}+999\frac{3}{7}+999\frac{4}{7}+999\frac{5}{7}+999\frac{6}{7}$$ is equal to:
Solution
We can write $$999\frac{1}{7}+999\frac{2}{7}+999\frac{3}{7}+999\frac{4}{7}+999\frac{5}{7}+999\frac{6}{7}$$ as,
=$$999+\frac{1}{7}+999+\frac{2}{7}+999+\frac{3}{7}+999+\frac{4}{7}+999+\frac{5}{7}+999+\frac{6}{7}$$
=$$999\times\ 6+\frac{\left(1+2+3+4+5+6\right)}{7}$$
=$$5994+3$$
=$$5997$$
