Question

What is 18 rounded to the nearest ten

Answer 1

Answer:

20

Step-by-step explanation:

When we round to the nearest ten, we will round up to a number that has a zero in the ones place but we have to look at the number in the ones place before we round to determine the number in the tens place. The rule is if the number in the place before the place we need to round (in this case the ones place would be what we look at to determine the rounded tens place) 1-4 is going to round down, keeping the tens place the same and the ones place goes to zero, and if the ones number place is 5-9 then we round up, bringing the ones to zero and the tens up by one tens place.

Answer 2

18 rounded to the nearest ten is 20.

Step-by-step explanation:

• The tenth position is two spaces to the left of the decimal point (if it exists). We utilize the whole numbers place to determine whether the tens place rounds up or stays the same when rounding to the nearest ten (nearest 10).

Step 1: Look to the right and locate and underline the tens place (1) (8)

Step 2: The digit on the right (8) in this case is 5 or above. As a result, we add one to the tens place (1).  

We get 20 as the solution because the digit(s) at the right (8) becomes 0.
