Question

What three choices are equal to 4x5

Answer 1

Answer:

The correct choice = 5 + 5 + 5 + 5

Step-by-step explanation:

The given statement is 4 x 5

To find the value of 4 x 5

4 x 5 means that,

Either adding number 4 in five times or adding the number 5 in four times

1). 4 x 5 = 4 + 4 + 4 + 4 = 20

2). 5 + 5 + 5 + 5 = 20

In both the way the answer is correct.

Therefore we can conclude that,

either we have to write 4 x 5 = 4 + 4 + 4 + 4 +4

or 4 x 5 = 5 + 5 + 5 + 5

In the given choices only one correct answer, that is 5 + 5 + 5 + 5

Answer 2

Answer:

5+5+5+5

4+4+4+4

5*4

Step-by-step explanation:

1. You have the following multiplication given in the problem above is:

4*5

Then, the product is:

4*5=20

2. The multiplication indicates that the number 4 is added five times,as following:

4+4+4+4+4=20

 3. The multiplication also indicates that the number 5 is added four times,as following:

5+5+5+5=20

4. The commutative property says that you can change the order of the factors but the product does not change:

5*4=20
