Question

4 upon 9 into minus 5 upon 18 minus 4 upon 15 into 3 upon 2 + 6 upon 5 into 4 upon 9​

Answer 1

Answer:

$\frac{104}{405}$

Step-by-step explanation:

$\frac{4}{9} \times \frac{5}{18} - \frac{4}{15} \times \frac{3}{2} + \frac{6}{5} \times \frac{4}{9} \\ = \frac{10}{81} - \frac{4}{10} + \frac{8}{15} \\ lcm = 810 \\ = \frac{100 - 324 + 432}{810} \\ = \frac{208}{810} \\ = \frac{104}{405}$
