Question

Match the expressions on the right with the results on the right.

Some options on the right will be used more than once.

Answer 1

416 ÷ 100 = 4.16

4.16 ÷ 10 = 0.416

41600 ÷ 1000 = 4.1600 = 4.16

4.16 ÷ 100 = 0.0416

41.6 ÷ 100 = 0.416

When you divide by a power of 10, you move the decimal to the left the number of 0's in the number.

÷ 10 and you move the decimal point 1 place to the left

÷ 100 and you move the decimal point 2 places to the left

÷ 1000 and you move the decimal point 3 places to the left

Answer 2

416 / 100 = 4.16

4.16 / 10 = 0.416

41600 / 1000 = 41.6

4.16 / 100 = 0.0416

41.6 / 100 = 0.416

Explanation:

When you divide a number by another number, you find out how many times the second number fits into the first one. For example, in the expression 416 / 100, you are finding out how many times 100 fits into 416. The answer is 4.16, meaning 100 fits into 416 4 times with a remainder of 16.

Similarly, in the expression 4.16 / 10, you are finding out how many times 10 fits into 4.16. The answer is 0.416, meaning 10 fits into 4.16 0 times with a remainder of 4.16.

In the expression 41600 / 1000, you are finding out how many times 1000 fits into 41600. The answer is 41.6, meaning 1000 fits into 41600 41 times with a remainder of 600.

In the expression 4.16 / 100, you are finding out how many times 100 fits into 4.16. The answer is 0.0416, meaning 100 fits into 4.16 0 times with a remainder of 4.16.

In the expression 41.6 / 100, you are finding out how many times 100 fits into 41.6. The answer is 0.416, meaning 100 fits into 41.6 0 times with a remainder of 41.6.
