Dividing Decimals by Whole Numbers
Today we will… Divide a decimal by a whole number. Review rounding a decimal to the nearest tenth.
Step 1 Place the decimal point in the quotient above the decimal point in the dividend. .
Step 2 Divide as with whole numbers. 6.6 -24 24 -
Step 3 Check your answer. Multiply the quotient by the divisor. Your answer should be the dividend. 6.6 X 4 26.4
Now try these two. 42.8 2.61 How did you do?
Let’s try rounding to the nearest 10th.Look at the number to the right of the number in the 10ths place. If it is 0, 1, 2, 3, or 4, round down. If it is 5, 6, 7, 8, or 9, round up. .925 rounds to .9 3.467 3.5 26.45 26.5 4.01 4 325.23 325.2
