Question

Add the following - 4/9,7/12and - 3/8​

Answer 1

Answer:

$- \frac{17}{72}$

Step-by-step explanation:

$- \frac{4}{9} + \frac{7}{12} + ( - \frac{ 3}{8} )$

When there is a (+) in front of an expression in parentheses, the expression remains the same:

$- \frac{4}{9} + \frac{7}{12} - \frac{3}{8}$

$\frac{ - 4 \times 8 + 7 \times 6 - 3 \times 9}{72}$

Calculate the sum of difference

$\frac{ - 32 + 42 - 27}{72}$

$\frac{10 - 27}{72}$

$- \frac{17}{72}$

Hope this helps..

Good luck on your assignment...
