Question
Choose the multiplication fact which is the same as 3 × 2 plus 1 × 2.
- 4 × 4 = 16
- 4 × 2 = 8
- 4 × 1 = 4
- 3 × 2 = 6
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: 4 × 2 = 8
In the question it is given that we have to find that among the options which is a match of 3×2 plus 1×2.
3×2 plus 1×2
= (3×2) + (1×2)
= 6+2
=8
=4×2
So, the expression that matches with the given expression is 4×2=8.
Therefore, the correct option is b, i.e., 4×2=8.
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.
