Answer:
1 1/3
Step-by-step explanation:
Find the common denominator of all three which is 6.
Then multiply each to make the common denominator 6
1/2*3 = 3/6
2/3*2 = 4/6
1/6*1 = 1/6
Then add all of them together
3/6+4/6+1/6 = 1 2/6
Simplified equals 1 1/3
To get the reciprocal, simply flip the numerator and denominator. The reciprocal of 3/10 is 10/3.
To get the answer we can use proportion
8 ginger ----------------- 3 fruit
12 ginger ----------------x
Crossmultiply now
8x=12*3 /:8
x=
![\frac{12*3}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B12%2A3%7D%7B8%7D%20)
x=<u />
![\frac{36}{8} \\ x=4.5](https://tex.z-dn.net/?f=%20%5Cfrac%7B36%7D%7B8%7D%20%20%5C%5C%20x%3D4.5)
To not change ratio we have to have 4.5 cups of fruilt juice. We initialy had 3, so we have to add 1.5 cup of fruit juice.
