1 1/4 teaspoons baking powder per 3/8 cup flour, what is the unit rate

5/4 teaspoons per 3/8 cup

1 teaspoon per (3/8)÷(5/4) or (3/8)(5/4) or 15/32 cup

or 1 teaspoon per 1/2 cup, after all , how "accurate" is the measure of a "teaspoon"

Well, that's quite a mouthful! Let's break it down. We have 1 1/4 teaspoons of baking powder per 3/8 cup of flour. To find the unit rate, we need to simplify this ratio.

First, let's convert the mixed number 1 1/4 to an improper fraction, which is 5/4. So, we have 5/4 teaspoons of baking powder per 3/8 cup of flour.

To find the unit rate, we need to have a ratio with 1 in the denominator. So, let's multiply both the numerator and denominator by 1/3 to get a denominator of 1.

(5/4) * (1/3) = 5/12

So, the unit rate is 5/12 teaspoons of baking powder per 1/8 cup of flour.

But since we're dealing with baking powder and flour here, it's important to remember that these measurements might not be as precise as we are making them out to be. So, take this unit rate with a pinch of baking humor!

To find the unit rate, we need to determine the ratio of baking powder to flour. In this case, the ratio is given as 1 1/4 teaspoons of baking powder per 3/8 cup of flour.

Next, we'll convert the mixed number, 1 1/4, to an improper fraction. To do that, we multiply the whole number, 1, by the denominator, 4, and add the numerator, 1. This gives us 1 * 4 + 1 = 5. So, 1 1/4 is equivalent to 5/4.

Now, we can set up the ratio:

(5/4) teaspoons of baking powder : (3/8) cup of flour

To convert this ratio to a unit rate, we consider the base unit. In this case, we'll use "teaspoons of baking powder per cup of flour."

To do that, we'll multiply the denominator of the flour by 2 to make it 8/8 cup. This gives us:

(5/4) teaspoons of baking powder : (3/8) cup of flour

Now, the ratio becomes:

(5/4) teaspoons of baking powder : (3/8 x 2/2) cup of flour
(5/4) teaspoons of baking powder : (6/8) cup of flour

Simplifying the ratio further, we have:

(5/4) teaspoons of baking powder : (3/4) cup of flour

The unit rate is therefore 5 teaspoons of baking powder per 3/4 cup of flour.

The unit rate of 5/4 teaspoons per 3/8 cup of flour
