Question2. Rounded numbers always end with a 0 in the ones place, but compatible numbers can end with a or A. 1 or 2 B. 0 or 5
Studdy Solution
STEP 1
1. The problem is about understanding the difference between rounded numbers and compatible numbers.
2. Rounded numbers typically end with a 0 in the ones place.
3. Compatible numbers are numbers that are easy to work with mentally, often used in estimation.
STEP 2
1. Define rounded numbers.
2. Define compatible numbers.
3. Determine the possible endings for compatible numbers.
STEP 3
Rounded numbers are numbers that have been adjusted to the nearest ten, hundred, etc., and thus always end with a 0 in the ones place when rounded to the nearest ten.
STEP 4
Compatible numbers are numbers that are easy to compute with mentally. They are often used in estimation to simplify calculations.
STEP 5
Determine the possible endings for compatible numbers. Compatible numbers can end with a 0 or 5, as these numbers are easy to add, subtract, multiply, or divide mentally.
