Answer:
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.
