Question

78 x 66 + 78 x ____ = 78 x 100

Answer 1

Answer:

34

Step-by-step explanation:

Answer 2

Answer:

The missing number will be$34$.

$78 \times66 + 78 \times34 = 78 \times 100$

Step-by-step explanation:

Given: $78 \times66 + 78 \times? = 78 \times 100$

We have to find the missing value.

• By using the Bodmas rule, we are solving the above expression.
• As we know that the Bodmas rule is used to remember the order of operations to be followed while solving expressions in mathematics.

Where,

$\begin{array}{l}\mathrm{B}=\text{brackets}\\\mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}$

We are solving in the following way:

We have,

$78 \times66 + 78 \times? = 78 \times 100$

Let assume the missing number be$x$.

Then,

$78 \times66 + 78 \times x = 78 \times 100$

Solving the above,

$78 \times66 + 78 \times x = 78 \times 100$

$=>5148+78x=7800$

1. Now, we will separate the variables on one side and the constant on another side.
2. Then, we will simplify the equation.

$=>5148+78x=7800\\\\=>78x=7800-5148\\=>78x=2652\\\\=>x=\frac{2652}{78} \\\\=>x=34$

Therefore the missing number is$34$.

In this problem, we are assuming we have to find the missing value.

Q. Solve: $78 \times66 + 78 \times? = 78 \times 100$
