Question

using appropriate properties find 2 upon 5 multiply minus 3 upon 7 minus 1 upon 1 4 minus 3 upon 7 multiply minus 3 upon 5​

Answer 1

Answer:

$\frac{1}{ 70}$

Step-by-step explanation:

1. $\frac{2}{5} \times ( \frac{ - 3}{7} ) - \frac{1}{14} - \frac{3}{7} \times ( \frac{ - 3}{5} )$
2. Use BODMAS Rule
3. $( \frac{ - 6}{35} ) - \frac{1}{14} + \frac{9}{35}$
4. $- ( \frac{6}{35} + \frac{1}{14} ) + \frac{9}{35}$
5. $- ( \frac{84 + 35}{14 \times 35} ) + \frac{9}{35}$
6. $\frac{9 \times 14}{14 \times 35} - \frac{119}{14 \times 35}$
7. $\frac{126 - 119}{14 \times 35}$
8. $\frac{7}{14 \times 35}$
9. $\frac{1}{2 \times 35}$
10. $\frac{1}{70}$
