Further explanation  

Fraction numbers are known as numerators and denominators  

On a number line, fractions are expressed in points that lie between two integers  

The general form of fractions is  

$\large {\boxed {\bold {\frac {a} {b}}}$  

a = numerator  

b = denominator  

There are 3 forms of fraction  

• 1. proper fraction  

• 2. improper fraction  

• 3. mixed fraction  

Mixed fractions consist of whole numbers and proper fractions  

Improper fraction has a top number larger/equal than the bottom number

To multiply Mixed Fractions and whole numbers :

1. Convert to Improper Fractions

2. Multiply the numerators  

3. Multiply the denominators  

4. Simplify the fraction  

For multiplying fractions and whole numbers,  

1. Make the whole number a fraction (denominators = 1)  

2. Multiplying fractions  

Steve drove for 8 1/2 hours at 72 miles per hour

• Convert 8 1/2 to Improper Fractions

$\displaystyle 8\frac{1}{2}--->\frac{17}{2}$

• Make the whole number a fraction (denominators = 1)

$\displaystyle 72=\frac{72}{1}$

• Multiply the numerators and denominators  

$\displaystyle \frac{17}{2}\times \frac{72}{1}$

$\displaystyles =\dfrac{1224}{2}\\\\=\boxed{\bold{612}}$
