The first step is:
Multiply the mixed numbers.
To do that, we must convert them into improper fractions.
[tex]3\frac{1}{2}[/tex][tex]+2\frac{2}{3} \\\\[/tex]
HOW TO DO IT:
Multiply the whole number by the denominator and add the numerator:
[tex]\frac{7}{2}[/tex]
Now we do the same thing with the other number:
[tex]\frac{8}{3}[/tex]
[tex]\frac{7}{2} *\frac{8}{3}[/tex]
Now, we just multiply the numerators by the denominators:
[tex]\frac{56}{6}[/tex]
If we divide, we get this:
9.3333333333...
So the estimate of the product must be 12.
