Help with an equation?

Question

I need help with this equation.

A recipe for bread calls for 3 2/3 cups of flour. The baker only wants to make half the recipe how much flour is needed.

I have looked all through my textbook and I can't find anything like this. Please explain how this one is done and I should be able to figure out the other equations like it.

Answer 1

5.5/3 of a cup in other words 1.83 of a cup

Answer 2

You need to find one half of the ingredients that are called for.

First, instead of being mixed numbers, make in an improper fraction. From there, take half of the numerator (this is the same as doubling the denominator) From there, reduce!

For example: Recipe calls for 9 and 5/8 flour. He wants to make one third of the recipe:

(5 + 9*8) / 8 = 77 / 8

One third of that value is (77 / 3) / 8 = 77 / 24

Reduce: 3 and 5/8 flour are needed

Answer 3

Half of 3 is 1 and 1/2. Half of 2/3 is 1/3. 1/2 + 1/3 = 5/6 (using common denominator, 6). So Half is 1 and 5/6.

Answer 4

3 2/3 = 11/3 = 22/6
(22/6)/2 = (11)/6 = 1 5/6

Answer 5

Here is one way to think about it. Turn 2/3 into a decimal. 2 divided by three. Than add the three and divide the whole thing by 2.


hope that helps.
