Meg makes a flour blend at home using barley and wheat flour in a ratio of 2: 3. how many ounces of barley does she use when she uses 27 ounces of wheat flour?

18 ounces of barley

Step-by-step explanation:

If Meg uses barley and wheat flour in a ratio of 2:3, we can set up equivalent ratios in order to find how many ounces of barley Meg would need if she uses 27 ounces of wheat flour:

= =

We can solve for 'x' (the number of ounces of barley) using a few different methods.  We can cross-multiply and divide:  27(2) = 3x, or x = 18.  We can also see what factor we multiply the 3 by to get 27 and multiply the numerator (2) by the same number.  Since 3 x 9 = 27, then 2 x 9 = 18.  

answer: the answer to your question is parallel

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
