Which is the smallest ratio? 3 to 4, Two-thirds, 10:12, 2 to 1
3 to 4
Two-thirds
10:12
2 to 1

Each ratio can be rewritten as a fraction:

3 to 4 becomes 3/4

2/3 is already a fraction

10:12 becomes 10/12 which can be simplified to 5/6 by dividing both the numerator and the denominator by 2

2 to 1 is 2/1 or 2

2 to 1 is the greatest because it is the only whole number. Comparing the three remaining can be a little more difficult because they have different denominators (the number on the bottom of the fraction).

In order to compare them we can find equivalent(equal) fractions that have a common denominator.

In order to find equivalent fractions we first find the common denominator. Then we multiple the fraction by a unit of one (ex. 2/2, 3/3, 4/4).

3/4 ,2/3, 10/12 12 would be a common denominator because 4 x 3 =12 3 x 4=12 and 12 x 1=12

3 x 3 = 9 3/4=9/12

4 x 3 = 12 2/3=8/12

10/12= 10/12

2 x 4 = 8

3 x 4 =12

Now that they have the same denominator we can see that 8/12 or 2/3 is the smallest fraction.

So, 2/3 is the smallest ratio

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3
