Mrs. Meier had 3/5 kg of sugar. She used 1/4 of it to make cookies. How much sugar did she use to make the cookies?

1/4 * 3/5 = 3/20 kg

To solve this problem, we will follow these steps:

Step 1: Convert the given values to fractions:
- Mrs. Meier had 3/5 kg of sugar.
- She used 1/4 of it to make cookies.

Step 2: Multiply the fractions:
- Multiply 3/5 kg by 1/4.

Step 3: Simplify the answer, if possible.

Let's calculate the solution.

Step 1: Given values:
- Mrs. Meier had 3/5 kg of sugar.
- She used 1/4 of it to make cookies.

Step 2: Calculation:
- Multiply 3/5 kg by 1/4:
(3/5) * (1/4) = (3 * 1) / (5 * 4) = 3/20

Step 3: Answer:
- Mrs. Meier used 3/20 kg of sugar to make the cookies.

Therefore, Mrs. Meier used 3/20 kg of sugar to make the cookies.

To find out how much sugar Mrs. Meier used to make the cookies, we can multiply the amount of sugar she had by the fraction of it she used.

First, let's convert the fractions into a common denominator. The smallest number that both 5 and 4 can divide into is 20.

So, 3/5 kg is equal to (3/5) * (4/4) kg, which is 12/20 kg.

And 1/4 of the sugar is equal to (1/4) * (5/5) kg, which is 5/20 kg.

Now, we can calculate how much sugar Mrs. Meier used by multiplying the amount she had (12/20 kg) by the fraction she used (5/20 kg):

(12/20 kg) * (5/20 kg) = (60/400) kg = 0.15 kg

Therefore, Mrs. Meier used 0.15 kg of sugar to make the cookies.
