Question

18 tens 20 ones equal what hundreds

Answer 1

Answer:

The answer is 2 hundreds.

Step-by-step explanation:

In order to determine the answer, we have to know about the notation numbers. In any number, every digit has a notation, depending on its position in the number.

I have attached an image that shows some notation numbers.

According to the image, we can see that:

"tens" means 10

"ones" means 1

So if a number is together to this notation, we can multiply both of them:

18 tens= 18 x 10= 180

20 ones= 20 x 1= 20

Adding both numbers:

180+20=200

Then, we need to know about "hundreds":

"hundreds" means 100

So, if we have 200, it is the same that 2 hundreds.

Finally the answer is 2 hundreds.
