### C. Rounding off Quotients

In this example of division, you can never reach a reminder of zero. In such cases, the quotient is usually rounded.

(a) 2.5÷3 = ?

0.83 rounded off to the nearest tenth is 0.8 since the digit in the hundredths place in less than 5.

2.5÷3 = 0.8

(b) 5.43÷8 = ?

0.678 rounded to the nearest hundredth is 0.86, since the thousandths place is more than 5.

5.43÷8 = 0.68

(c) 0.75 rounded to the nearest tenth = 0.8

(d) 1.592 rounded to the nearest hundredth = 1.59

**Division by 10, 100, 1000**

Look for a pattern. Watch the decimal points.

(a) 821.5÷10 = 82.15

(b) 821.5÷100 = 8.215

(c) 821.5÷1000 = 0.8215

What do you observe?

**When dividing by**

**The decimal point moves to the left by**

Remember this rule by counting the zeros. Move the decimal point to the left as many places as there are zeros.

(d) 4÷10 is the same as 4.0÷10.

So 4÷10 = o.4

(e) 2.35÷100 = 0.0235
