Answer 2

Let's solve these two arithmetic expressions step by step:

1. -2 1/4 + (-1 1/4):

To add these two mixed numbers, we first add the whole numbers and then add the fractions separately.

-2 + (-1) = -3 (whole numbers)

1/4 + 1/4 = 2/4 (fractions)

Now, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:

2/4 ÷ 2/2 = 1/2

So, the result is:

-3 + 1/2 = -3 1/2

2. 1 1/3 - 7 2/3:

To subtract these two mixed numbers, we first subtract the whole numbers and then subtract the fractions separately.

1 - 7 = -6 (whole numbers)

1/3 - 2/3 = -1/3 (fractions)

So, the result is:

-6 - 1/3 = -6 1/3
