Let's simplify the expression step by step:
-30/3115/124 = -450/3844-16/21(-7/8) = 112/168Now we can add these two results together:
-450/3844 + 112/168 = -450/3844 + 896/3844= (896 - 450) / 3844= 446/3844
Therefore, -30/3115/124 + (-16/21)(-7/8) simplifies to 446/3844.
Let's simplify the expression step by step:
-30/3115/124 = -450/3844
-16/21(-7/8) = 112/168
Now we can add these two results together:
-450/3844 + 112/168 = -450/3844 + 896/3844
= (896 - 450) / 3844
= 446/3844
Therefore, -30/3115/124 + (-16/21)(-7/8) simplifies to 446/3844.
