Question

485 + 648 + 515 = 648 + (______ + ________) = _________

Answer 1

485+648+515=648+(485+515)=1648

Answer 2

To find the missing values in the equation, we can solve step by step:

Step 1: 485 + 648 + 515 = 1648

Step 2: Now, let's represent the second part of the equation as 648 + (x + y) = z, where x and y are the missing values we need to find, and z is the sum of the second part.

Step 3: To find x + y, we can subtract 648 from both sides of the equation:

648 + (x + y) - 648 = z - 648

Step 4: The 648 on the left side cancels out, and we get:

x + y = z - 648

Step 5: Now, we know that z is the same as the sum we found in Step 1, which is 1648:

x + y = 1648 - 648

Step 6: Now, let's calculate the value of x + y:

x + y = 1000

So, the missing values are x + y = 1000, and the complete equation is:

485 + 648 + 515 = 648 + (x + y) = 1648
