Mixed Numbers in Applications
Key Questions

When multiplying mixed numbers they have to be either converted to improper fractions or to their decimal equivalent.
#2 1/2*3 3/4=5/2*15/4=75/8=9 3/8# or
#2 1/2*3 3/4=2.5*3.75=9.375=9 375/1000=9 3/8# DO NOT
just multiply the whole number part
just multiply the fractional parts 
Conversion of Centigrade temperature to Fahrenheit.
#F = (9/5)*C + 32# 
A mixed number is one in which there is a whole number combined with a fraction. Examples include 1 1/2, 3 2/3, and 6 4/9. They can be converted into improper fractions by multiplying the denominator of the fraction times the whole number and adding the numerator, then placing the result over the denominator.
Examples
1 1/2 = 2 x 1 +1 =3/2
3 2/3 = 3 x 3 +2 = 11/3
6 4/9 = 9 x 6 + 4 = 58/4 = 29/2
