The answer is -3.7. Plug in -2.5 into the expression. Then the expression is rewritten as 2.2 - 2.5 - 3.4. Subtract -2.5 from 2.2 and you get -.3. Now, the expression is -.3 - 3.4. Subtract those from each other and you get -3.7.

861 ÷3 show work for this problem please

TEA [102]

861 divided by 3:

How many times does 3 go into 8? 2 x 3 = 6
Subtract 6 from 8 to get a remainder of 2, and bring down 6 to get 26.

How many times does 3 go into 26? 8 x 3 = 24
Subtract 24 from 26 to get a remainder of 2, and bring down 1 to get 21.

How many times does 3 go into 21? EXACTLY 7 times. 7 x 3 = 21

Collect all numbers in bold to get…. 287!

Therefore, 861 divided by 3 = 287.
