Question

Len uses 3 1/4 teaspoons of chili powder for a batch of chili. He wants to divide this recipe by 2. How much chili powder should be use?

Answer 1

Answer:

Tea spoons of chili powder Len should use =$\frac{13}{8} =1\frac{5}{8}$  

Explanation:

 Chili powder used by Len for a batch of chili = $3\frac{1}{4}=\frac{3*4+1}{4} =\frac{12+1}{4} =\frac{13}{4}$ tea spoons

 Number of divisions Len need to make = 2

 Amount of chili powder in 1 division = Total chili powder/ Number of divisions.

  So chili powder Len should use = $=\frac{(\frac{13}{4}) }{2} =\frac{13}{8} =1\frac{5}{8}$ tea spoons

 Tea spoons of chili powder Len should use =$\frac{13}{8} =1\frac{5}{8}$
