Answer 1

Answer:

-Word form: $Thirty-two\ and\ fifteen\ houndreths$

-Unit form: $3\ tens\, 2\ ones, 1\ tenth,\ 5\ hundreths$

-Expanded form:

Using fractions:

$3*10+2*1+\frac{1}{10}+\frac{5}{100}$

Using decimals:

$3*10+2*1+1*0.1+5*0.01$

Step-by-step explanation:

You can observe that the measure of the edge of the dining table is a decimal number:

$32.15\ meters$

Word form

- Write in words the digits to the left of the decimal point as a whole number.

- The decimal point expressed in words is "and".

-  Write in word the digits to the right of the decimal point as a whole number.

- Write in words the place value of the last digit to the right of the decimal point.

Therefore, this is:

$Thirty-two\ and\ fifteen\ houndreths$

Unit form

Write the place value of each digit within the number:

$3\ tens\, 2\ ones, 1\ tenth,\ 5\ hundreths$

Expanded form

 Write the place value of each digit.

Using fractions:

$3*10+2*1+\frac{1}{10}+\frac{5}{100}$

Using decimals:

$3*10+2*1+1*0.1+5*0.01$
