Simplify:
(13/9×-15/2)+(7/3×8/5)(3/5×1/2)
Answers!
(13/9 × 15/2) + (7/3 × 8/5)(3/5 × 1/2)
= (13 × 15)/(9 × 2) + (7/3 × 8/5 × 3/10)
= 195/18 + (7 × 8 × 3)/(3 × 5 × 10)
= 65/6 + 56/50
= 65/6 + 28/25
Now, taking LCM (150):
= (65 × 25)/(6 × 25) + (28 × 6)/(25 × 6)
= 1625/150 + 168/150
= 1793/150

Answer the question...
(13/9 × 15/2) + (7/3 × 8/5)(3/5 × 1/2)
= (13 × 15)/(9 × 2) + (7/3 × 8/5 × 3/10)
= 195/18 + (7 × 8 × 3)/(3 × 5 × 10)
= 65/6 + 56/50
= 65/6 + 28/25
Now, taking LCM (150):
= (65 × 25)/(6 × 25) + (28 × 6)/(25 × 6)
= 1625/150 + 168/150
= 1793/150
= (13 × 15)/(9 × 2) + (7/3 × 8/5 × 3/10)
= 195/18 + (7 × 8 × 3)/(3 × 5 × 10)
= 65/6 + 56/50
= 65/6 + 28/25
Now, taking LCM (150):
= (65 × 25)/(6 × 25) + (28 × 6)/(25 × 6)
= 1625/150 + 168/150
= 1793/150
