Question
Evaluate given expression using distributive property 7 × 3 + 11.
- 21
- 32
- 80
- 98
Hint:
Distributive property is the law in which we can solve problems which are in the form a(b+c). To solve this type of problem we just have to multiply a with b and then c which can be written as ab+ ac and then finally add them. It is one of the common formula which is used to solve problems. Here, we have to solve the problem using distributive property.
The correct answer is: 98
In the question the given expression is 7 × 3 + 11 using distributive property.
Here, we have to solve 7 × 3 + 11 using distributive property.
We can write 7 as 4+3.
So, on using distributive property of multiplication,
7 × 3 + 11
= (4+3) × 3 + 11
=(4×3)+(3×3) + 11
= 12+9+11
=32
So, the answer for the expression will be 32.
Therefore, the correct option is b, i.e., 32.
In distributive property, when a factor is to be multiplied with the sum of two numbers, we do not directly add the two numbers and then multiply the sum with the factor. Rather, we multiply both the numbers with the factor differently and then add the multiplication value.
