Answer:
7/3
Step-by-step explanation:
What you do when you divide is you need to switch the second number and turn the division sign into a multiplication sign.
<em>4 2/3 / 2.</em>
<em>4 2/3 * 1/2=</em>
7/3 as your answer.
Make it so that the fractions have common denominators. 12 is a common denominator we can use.
5/6= 10/12 1/4= 3/12
Multiply both numbers by 2. Multiply both by 3.
Now, add.
4 10/12+ 5 3/12= 9 13/12
Simplify.
10 1/12.

Step-by-step explanation:
Answer:
- 40 ml of water must be added.
Step-by-step explanation:
Initial volume of mixture is 100 ml with oil to water ratio of 1 : 4.
First, let's find the volume of each component.
If the oil is x then water is 4x according to ratio and their sum is 100 ml:
- x + 4x = 100
- 5x = 100
- x = 20
So, we have 20 ml of oil and 80 ml of water.
Now, let's added volume of oil be y. Then we have the ratio:
- (20 + y)/80 = 1/2
- 20 + y = 40
- y = 20
So, we have 40 ml of oil and 80 ml of water.
Lastly, let's added water be z. Then we have the ratio:
- 40/(80 + z) = 1/3
- 80 + z = 120
- z = 40
We must add 40 ml of water.
