Answer 2

Let's solve each of these math problems step by step:

1. -4.3 + 1.6 = -4.3 + 1.6 = -2.7

2. -2 1/6 - (-3) To subtract a negative number, you can change it to addition: = -2 1/6 + 3 Now, find a common denominator, which is 6: = (-12/6) + (18/6) = (-12 + 18)/6 = 6/6 = 1

3. 7 5/8 - 9 1/4 To subtract mixed numbers, first find a common denominator, which is 8: = (7 * 8 + 5)/8 - (9 * 2 + 1)/4 = (56 + 5)/8 - (18 + 1)/4 = 61/8 - 19/4

Now, let's find a common denominator, which is 8: = (61/8) - (38/8) = (61 - 38)/8 = 23/8

4. -4.13 - 2.1 = -4.13 - 2.1 = -6.23

5. -15 - (-0.3) + 1.7 To subtract a negative number, you can change it to addition: = -15 + 0.3 + 1.7 = (-150/10) + (3/10) + (17/10) = (-150 + 3 + 17)/10 = (-150 + 20)/10 = -130/10 = -13

So, the solutions to the given problems are:

1. -2.7
2. 1
3. 23/8
4. -6.23
5. -13
