**Multiplication
of decimals is very similar to the way we multiply whole numbers.**

**The question is
how many decimal places are in the answer. Lets look at an example.**

**45.67 x 2.09 = ? How many decimal places are in the answer?**
**
Estimate what the answer should be.**

**
45.67**
**
x 2.09**

**Try these examples:**
**
1) .0009 x 6.7 = ? (try to estimate
your**
**
answer, will it be less**
**
or greater than 6.7 , less or greater **
**
than 1 ?) answer**

**
2) 6.3(.1) = ? (try to estimate
your answer,**
**
and answer the same questions**
**
asked for # 1) answer**

** **
**What happens to the decimal point when we multiply the following:**
** **
**
4.5678 x 10 = 45.678**
**
4.5678 x 100 = 456.78**
**
4.5678 x 1000 = 4567.8**
**
4.5678 x 10000 = answer**

**Question: Can your answer be greater than 1 if both factors**
**are less than 1 ? Make up an example and use it to try to
answer**
**that questions, then check the answer. answer**
