Qt A
\(\frac{5}{14} + \frac{8}{21}\)
Take the LCM
\(\frac{75 + 80}{210} = \frac{155}{210}\)
Qt B
\(\frac{26}{35} - \frac{3}{14}\)
Take the LCM
\(\frac{126 - 45}{210} = \frac{81}{210}\)
Qt A > Qt B
Answer A
\(\frac{5}{14} + \frac{8}{21}\)
Take the LCM
\(\frac{75 + 80}{210} = \frac{155}{210}\)
Qt B
\(\frac{26}{35} - \frac{3}{14}\)
Take the LCM
\(\frac{126 - 45}{210} = \frac{81}{210}\)
Qt A > Qt B
Answer A

5/14 + 8/21 ? 26/35 - 3/14
5/2 + 8/3 ? 26/5 - 3/2 --------(multiply all with 7)
(15+16)/6 ? (52-15)/10
31/6 ? 37/10
5.xx ? 3.7
So Qt A > Qt B
5/2 + 8/3 ? 26/5 - 3/2 --------(multiply all with 7)
(15+16)/6 ? (52-15)/10
31/6 ? 37/10
5.xx ? 3.7
So Qt A > Qt B
