She needs to add one half of a teaspoon of salt, 1 and one fourth teaspoons of Oregano, three fourths of a teaspoon of Basil and half as much pepper as salt. What is the total number of teaspoons of spices in the dish? Express the answer as a decimal.

Total number of teaspoons is 2.75

Step-by-step explanation:

Here, we want to know the total number of teaspoons of spices in the dish

we can calculate this by adding together the individual number of spices

That will be ;

1/2 + 1 1/4 + 3/4 + 1/2(1/2)

1/2(1/2) represents half as much pepper as salt

1/2 = 0.5

1 1/4 = 1.25

3/4 = 0.75

1/2(1/2) = 1/4 = 0.25

The total number of tea spoons will be;

0.5 + 1.25 + 0.75 + 0.25 = 2.75

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
