Question

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 be so spicy. How much chili powder should Karl use?

Answer 1

`(3)/(8) / (2)/(1) \\ = (3)/(8) * (1)/(2) \\ = (3)/(16)`
3/16

you set it up as a normal division problem then use KCF

keep the first term the same change the sign to a multiplication and flip the last term and use the inverse

Answer 2

He should use
`(3)/(16)` cups of chili powder.

Explanation:

Given,

The total quantity of chili powder =
`(3)/(8)` cups,

Also, only half of the chilli powder is used,

So, the used quantity of chilli powder =
`(1)/(2)* (3)/(8)`

`=(3)/(16)` ( Multiplication of fractions ),

Hence, he should use
`(3)/(16)` cup of chili powder.
