MONDAY IS TEST

A little Riddle….

“Line up your decimals, add in your zeroes, find the sum, don’t be a bum…..line up your decimals, add in your zeroes, now it’s time to subtract, don’t get this out of wack”

Dividing Decimals 1. Set up divisor and dividend correctly 2. Look at the Divisor, move decimal place over to make a whole number

3. However many places you moved the decimal in step 2, you move the decimal in the dividend 4.Divide as you would with a whole number

Just Watch 1.80 ÷ .06
