To solve this expression, we need to add/subtract the whole numbers separately from the fractions:
12 - 7 + 15 = 20
8/15 + 7/15 = 15/15 = 1
Putting the whole number and the fraction together, we get:
20 + 1 = 21
So, the correct answer is 2) 21.

how should you group the following expression to make it easiest to add? 18 - 9 4/9 + 7/9 - 8
1) (18 - 9 - 8) + (-4/9 + 7/9)
2) (8 - 18) + (4/9 + 7/9)
3) (18 - 8) + (9 4/9 + 7/9)
4) (18 - 8 - 9)
which is the correct answer
1) (18 - 9 - 8) + (-4/9 + 7/9)
2) (8 - 18) + (4/9 + 7/9)
3) (18 - 8) + (9 4/9 + 7/9)
4) (18 - 8 - 9)
which is the correct answer
The correct answer is 1) (18 - 9 - 8) + (-4/9 + 7/9).
By grouping the terms in this way, we first subtract 9 from 18 and then subtract 8 from the result. After that, we add the fractions (-4/9 + 7/9) together.
This grouping helps to simplify the expression and make the addition easier to do.
