Answer:
Fred is [tex]\frac{17}{24}[/tex] ft taller than Benny
Step-by-step explanation:
Subtract Benny's height from Fred's height
4 [tex]\frac{1}{12}[/tex] - 3 [tex]\frac{3}{8}[/tex] ( change to improper fractions )
[tex]\frac{49}{12}[/tex] - [tex]\frac{27}{8}[/tex]
The LCM of 12 and 8 is 24 , then
= [tex]\frac{49(2)}{12(2)}[/tex] - [tex]\frac{27(3)}{8(3)}[/tex]
= [tex]\frac{98}{24}[/tex] - [tex]\frac{81}{24}[/tex]
= [tex]\frac{17}{24}[/tex]
