Question

A baker uses 2/3 cup of rye flour in each loaf of bread. How many cups of rye flour will the baker use in 3 loaves? in 7 loaves? in 10 loaves?

Answer 1

3 loaves? 2 rye flour

7 loaves? 4⅔ rye flour

10 loaves? 6⅔ rye flour

Explanation:

To get how many cups of rye flour the baker will use, for example: to get how many cups of rye flour the baker will use in 3 loaves? we multiply the number of cups the baker uses to make one loaf of bread

`3 \: loaves \: = (2)/(3) * 3`

`(2)/(3) * 3 = 2`

Now let's work out the others using the same method shown above

`(2)/(3) * 7 = 4 (2)/(3)`

`(2)/(3) * 10 = 6 (2)/(3)`

Hope that helps

Answer 2

2 cups = 3 loaves, 4 2/3 (4.66666667 in decimal form) cups of rye in 7 loaves, and 6 2/3 (6.66666666667 in decimal form) cups of rye in 10 loaves.

Explanation:

What do we know? We know that 2/3 cups of rye is equal to one loaf of bread. We need to figure out how many cups of rye are in three loaves, seven loaves, and ten loaves. To do this, we will first figure out how many cups of rye are in three loaves. Since we know that 2/3 cups of rye is in 1 loaf, we take 2/3 cups and multiply it by three over one, or, three, for the three loaves. That comes out to 6/3. Now, we simplify. Three goes into six, evenly, twice with no remainder. So, 2 cups of rye goes into 3 loaves. The decimal for this would be 2.0.

Applying the same method, 2/3 cups times 7. We get 14/3. Three goes into fourteen 4 times with a remainder of 2. So, the answer would be 4 2/3 cups of rye in 7 loaves. To get the decimal version, divide 14 into 3.

2/3 times 10 equals 20/3. 3 goes into twenty six times with a remainder of two. So, 6 2/3 cups of rye in 10 loaves. To get the decimal version, simply divide 20 into 3.
