Answer:
A. 20
Step-by-step explanation:
We know that there are 8 eights in a whole, and a whole is equal to the number 1. The number 2 consists of two wholes, and so we multiply 8 by 2.
8 wholes in each 1 × 2 ones = 16 wholes
Now, we know that the number 2 is equal to 16 wholes, so now we need to find how much 1/2 of a whole is worth.
1 whole = 8 eights, so divided by 2, it would be 4 eights for a half of a whole.
So, we add 16 + 4 to get the result of 20.
