Question

The sum of 1/11 and 1/15 is closest to....

Answer 1

$\frac{1}{11}+\frac{1}{15}=\frac{1\cdot15}{11\cdot15}+\frac{1\cdot11}{15\cdot11}=\frac{15}{165}+\frac{11}{165}=\frac{15+11}{165}=\frac{26}{165} < \frac{1}{2}\\\\\frac{1}{11}+\frac{1}{15}\approx0$

Answer 2

1/11=0.090
1/15=0.060
The sum of the two is 0.15
