Hello! So, 11/2 cups is simplified as 5 1/2 cups. In order to find out how many 1/8 cups Jenn will need to scoop, all you have to do is divide each number by 1/8. When you divide fractions, you keep the first fraction the same, change division into multiplication, and flip the second fraction over into it's reciprocal. So 2 / 1/8 becomes 2/1 * 8/1. With that being said, if you solve each of them correctly, here are your answers for the number of 1/8 cups needed.
Water: 16
Brown Rice: 44
Jenn willl have to use the 1/8 scoop to get water 16 times and the 1/8 scoop to get brown rice 44 times.
Answer:
p = q/5 - 9r/5
Step-by-step explanation:
Step 1: Write equation
5p + 9r = q
Step 2: Solve for <em>p</em>
<u>Subtract 9r on both sides:</u> 5p = q - 9r
<u>Divide both sides by 5:</u> p = q/5 - 9r/5
