If A $=\frac{18÷9×4}{15÷3×5}$ and B $=\frac{18÷36×3+5×1-6}{18÷6×20-3×4+12}$, then what is the value of (A + B) ?
Answer & explanation
Correct answer: option 4
If A $=\frac{18÷9×4}{15÷3×5}$
B $=\frac{18÷36×3+5×1-6}{18÷6×20-3×4+12}$
Then what is the value of (A + B) ?
A $=\frac{18÷9×4}{15÷3×5}$ = \(\frac{8}{25}\)
B $=\frac{18÷36×3+5×1-6}{18÷6×20-3×4+12}$ = $\frac{1÷2}{60}$
B = $\frac{1}{120}$
Put them in required equation,
(A + B) = \(\frac{8}{25}\) + $\frac{1}{120}$
(A + B) = \(\frac{192 + 5}{600}\)
(A + B) = $\frac{197}{600}$
