Question

Find the sum of each group of numbers. You may add the numbers in order.

Answer 1

Step-by-step explanation:

The complete question is given in a comment above. So we have three groups here:

a. 110, 83, and 328

b. 92, 37, 14, and 66

c. 432, 11, 157, and 30

So, by using associative property:

`a) \\ \\ 110+ 83+328=(110+83)+128=193+128=\boxed{521} \\ \\ \\ b) \\ \\ 92+37+ 14+66=(92+37)+ (14+66)=129+80=\boxed{209} \\ \\ \\ c) \\ \\ 432 + 11 + 157 + 30 = (432 + 11) + (157 + 30)=(443)+(187)=\boxed{630}`
