7.4–1.1)–(2.1–8.1)

Answer 1

0.3

Explanation:

(7.4-1.1) - (2.1-8.1)

Lets start with (7.4-1.1)

Step 1:

(7.4-1.1) =6.3 (All you do is subtract 7.4-1.1 and it gives you 6.3)

Step 2: Lets do (2.1-8.1)

(2.1-8.1)= -6 (2.1 minus 8.1 gives you -6 because 2.1 is smaller than 8.1 so it will give you a negative)

Step 3: Subtract

6.3-6

So your answer would be 0.3

Hope that helped :)
