Final answer:
To find the missing number in the equation 1.6 + ______ = 5 + 6, combine the constants to get 11 and then subtract 1.6 from both sides to find that the missing number is 9.4.
Step-by-step explanation:
To find the missing number in the equation 1.6 + ______ = 5 + 6, we first need to combine the numbers on the right side of the equation. Adding 5 and 6 gives us 11. Our equation now looks like 1.6 + ______ = 11.
Next, to find the missing number, we subtract 1.6 from both sides of the equation to isolate the missing number on one side. Therefore, 11 - 1.6 = 9.4. This means that the missing number in the equation is 9.4.
To summarize, we combine constant terms on one side, isolate the variable on the other, and perform the subtraction to find our missing number. This is a basic algebraic operation of solving one-step equations involving addition and subtraction. Remember that when working with equations, what you do to one side, you must do to the other to maintain balance.
