Question

2. Simplify 3/8 ÷ [-51/24+17/12]​

Answer 1

Answer:

3/8÷85/24

=3/8×24/85

=9/85

Answer 2

$\frac{3}{8} \div ( \frac{ - 51}{24 } + \frac{17}{12} ) \\ = \frac{3}{8} \div ( \frac{ - 51 + 34}{24} ) \\ = \frac{3}{8} \div ( \frac{ - 17}{24}) \\ = \frac{3}{8} \times \frac{ - 24}{17} \\ = \frac{ - 9}{17}$
