ROUNDING WHOLE NUMBERS

What is the main purpose of rounding numbers?

• To make numbers more precise

• To simplify calculations

• To increase number size

• To learn new number systems

What effect does rounding have on the original number?

• Makes it exactly the same

• Makes it more precise

• Makes it less precise

• Does not change it

What does rounding a number involve?

• Making the number more complex

• Creating a less precise version of the number

• Changing all digits to zeros

• Always rounding up

When rounding to the nearest ten, what would you do with the number 1,863?

• Round to 1,860

• Round to 1,900

• Round to 1,870

• Round to 1,800

Why might you not need exact precision for a dog's weight?

• Exact weight changes daily

• It's too hard to calculate

• Approximate weight is usually sufficient

• Dogs don't weigh much

What is the purpose of making a number less precise?

• To make it longer

• To change its numerical system

• To increase its value

• To make calculations easier

What happens to digits smaller than the 'target' when rounding?

• They are turned into zeros

• They are removed from the number

• They are increased by one

• They are left unchanged

What does the 'target' digit represent in rounding?

• The least significant digit

• The most significant digit

• The unchanged digit

• The digit to be rounded

What should you do if the digit next to the 'target' is less than 5?

• Round up

• Round down

• Leave it as is

• Increase it by one

What is the result of rounding 24,623 to the nearest hundred?

• 24,600

• 24,500

• 24,700

• 25,000
