Karl is making a pot of chili. The recipe calls for 3/8 cup of chili powder, but Karl only wants to use half as much so it won’t
tresset_1 [31]

Answer:

KArl should use 3/16 cups of chili powder

Step-by-step explanation:

Given that:

Recipe's requirement : 3/8 cups

Karl wants to use half : 1/2

The given question involves fractions. When the number of cups has to be divided into half, it will be multiplied with 1/2.

So,

Multiplying the chili powder requirement of the recipe to 1/2

=\frac{3}{8} * \frac{1}{2}\\= \frac{3}{16}

Hence,

KArl should use 3/16 cups of chili powder

Aimi is making Valentine’s Day cards for everyone in her class. She plans to use a whole sheet of paper for each of her 6 closes
DaniilM [7]
34 - 6 = 28
28 x 8 = 224

After making the 6 whole sheet of paper cards for her closest friends Aimi will have 28 pieces of paper left.

Since she wants to use 1/8 of a sheet per valentine (think of it as one piece of paper can make 8 valentines) you can do 28 pieces of paper multiplied by 8 which gives you 224 valentines.
