Question

Identify the missing numbers in the related equations below.
$16$ – __ $=9$ and $9+7=$ ___

• A. $6,16$
• B. $7,15$
• C. $7,16$
• D. $16,6$

Answer 1

The correct option is C $7,16$

The bigger number and the difference are given for the subtraction equation, whereas both the addends are given for the addition equation.
We know that when we subtract one of the addends from their sum, we get the other addend as the result.
Here, in the addition equation, $9$ and $7$ are the addends.



In the subtraction equation, we have $9$ as the difference and $16$ as the bigger numbers.
So, based on the addition equation, we can say that $7$ is the missing number in the subtraction equation and based on the subtraction equation, we can say that $16$ is the missing number in the addition equation.


Hence, Option A is correct, and $7$ and $16$ are the missing numbers in the equations.
