Answer:
6
Explanation:
This question is seeking for an equivalent of one expression. The first expression says 1/3 of 12, which means 1/3 × 12 = 4. To find 2/3 of a number that will give us 4, we say
Since; 1/3 of 12 is 4
Then, 4 = 2/3 of x, where x is the number, which when multiplied by two-third (2/3) will result to 4.
4 = 2/3 × x
4 = 2x/3
Cross multiply
2x = 3 × 4
2x = 12
x = 12/2
x = 6.
This means that; 1/3 of 12 = 2/3 of 6
Explanation:
- A homogeneous mixture is defined as the mixture in which solute particles are evenly distributed into a solvent.
For example, iced tea with no ice is a homogeneous mixture.
Also, a cheddar cheese contains even distribution of solute particles. Hence, it is also a homogeneous mixture.
- On the other hand, a mixture in which solute particles are unevenly distributed in a solvent is known as a heterogeneous mixture.
For example, both rocky road ice cream and trail mix are heterogeneous mixture.
It is a mixture, specifically a homogeneous mixture. It is the same composition all the way through. The concentrations of the dissolved substances are the same, so it is a mixture.
