First, you need to substitute y for 2/3:
2/3 • 6
Next, change 6 into a fraction and multiply straight across:
2/3 • 6/1
12/3
Finally, simplify it to its simplest form:
4
Your answer should be 4.
Hopefully that helped!
Hello, and thank you for posting your question here on brainly.
When you're dividing two fractions, there's a simple rule to follow.
You flip the second fraction, (aka reciprocal) and then multiply.
2/3 ÷ 1/4 = 2/3 * 4/1
You multiply across from the top and bottom.
2/3 * 4/1 = 8/3
8/3 = 2 2/3
Your final answer is C.
Hope this helps! ☺♥
Answer:
19% alcohol solution = 65 ounces
37% alcohol solution = 25 ounces
Step-by-step explanation:
Let
19% alcohol solution = x
37% alcohol solution = y
x + y = 90 (1)
0.19x + 0.37y = 90*0.24
0.19x + 0.37y = 21.60 (2)
from (1)
x = 90 - y
Substitute into (2)
0.19x + 0.37y = 21.60
0.19(90-y) + 0.37y = 21.60
17.1 - 0.19y + 0.37y = 21.60
- 0.19y + 0.37y = 21.60 - 17.1
0.18y = 4.5
y = 4.5/0.18
y = 25 ounces
x + y = 90 (1)
x + 25 = 90
x = 90 - 25
x = 65 ounces
