Skill: Represent the same money amount in different ways

The same money amount can be shown with coins, cents, or decimal dollars. Remember:

• $(100)$ cents equals $1$ dollar.
• The first digit after the decimal shows tenths, or dimes.
• The second digit shows hundredths, or cents.

Example: Represent $1$ dollar and $(37)$ cents in different ways.

1. Write it as decimal dollars:

   $1$ dollar and $(37)$ cents is 1.37$.

2. Write it as cents:

   Since $1$ dollar equals $(100)$ cents,

$$100+37=137$$

So the amount is $(137)$ cents.

3. Show it with coins:

   One possible combination is:

$$1\text{ dollar coin}+1\text{ quarter}+1\text{ dime}+2\text{ pennies}$$

Its value is

$$100+25+10+2=137\text{ cents}.$$

So these all represent the same amount:

$$\boxed{\$1.37=137\text{ cents}=1\text{ dollar}+1\text{ quarter}+1\text{ dime}+2\text{ pennies}}$$
