Answer:
Step-by-step explanation:
-2/5 - 4/5 + -9/10
= -2/5 - 4/5 - 9/10
= {-2(2) -4(2) - 9)/10
= (-4 - 8 - 9)/10
= -21/10
= -2 1/10

<span>Step 1. Let n be an integer.
Step 2. Let n+1 and n+2 be the next two consecutive integers.
Step 3. Let n+n+1=2n+1 be the sum of the two smallest integers.
Step 4. Let 2(2n+1) be twice the sum of the two smallest integers.
Step 5. Let 3(n+2) be three times the largest number
Step 6. Then using Steps 3 and 4, 2(2n+1)=3(n+2)+10 since twice the
sum of the two smallest numbers is 10 more than three times the largest
number.
Step 7. Solving yields the following steps:
