Question

-10+6,3;1+(-0,78);5/8+(-3/4);-5+3 1/2​

Answer 1

Ответ:

1) -3,7

2)0,22

3)-1/8

4)-1 1/2

Answer 2

Let's calculate the following expressions:

1. -10 + 6.3: -10 + 6.3 = -3.7

2. 1 + (-0.78): 1 + (-0.78) = 0.22

3. 5/8 + (-3/4): To add fractions, we need a common denominator. The common denominator for 8 and 4 is 8. So, we'll convert both fractions to have 8 as the denominator: 5/8 + (-3/4) = 5/8 - 6/8 = (5 - 6)/8 = -1/8

4. -5 + 3 1/2: To add a whole number and a mixed number, we first convert the mixed number to an improper fraction. 3 1/2 = 7/2 -5 + 7/2 = -10/2 + 7/2 = -3/2

So, the results are:

1. -10 + 6.3 = -3.7
2. 1 + (-0.78) = 0.22
3. 5/8 + (-3/4) = -1/8
4. -5 + 3 1/2 = -3/2
