Question

12 5/9-9 3/7-2 1/2+4 5/7​

Answer 1

Answer:

$5\frac{43}{126}$

Step-by-step explanation:

$12\frac{5}{9} - 9\frac{3}{7} - 2\frac{1}{2} + 4\frac{5}{7}$

= $\frac{113}{9} - \frac{66}{7} - \frac{5}{2} + \frac{33}{7}$

LCM of 2,7 and 9 = 126

= $\frac{1582 - 1188 - 315 + 594}{126}$

= $\frac{673}{126}$

= $5\frac{43}{126}$
