DIVISION

Ex. 323,400 ÷ 400 = N- Remove the same number of zeroes from the Divisor and Dividend323,400 ÷ 400 = N

Dividing Multiples of 10

- Divide the usual way3,234 ÷ 4 = 808 r2But, how about 456,000 ÷ 20?523,370 ÷ 300?

Dividing Multiples of 10

Ex. 3,924 ÷ 43 = N- Round-off the Divisor and Dividend to the nearest place value3,92443

Rounding-off Quotients

4,00040

- Divide the usual way4,000 ÷ 40 = 100(Therefore, 100 is the MOST REASONABLE ANSWER) Try these!!! Find the MOST REASONABLE ANSWER23,948 ÷ 46 = N593,059 ÷ 28 = N4,389,493 ÷ 54 = N
