Dora and Paul have a collecttion of x marbles.Dora has x/3.What is the fraction of the marbles does Paul have?

paul has x - x/3 or (2/3)x

(say that out-loud to yourself)

Hal's age is three times Ida's age.In 8 years Hal will be twice as Ida.How old is Hal?

To find the fraction of the marbles that Paul has, we first need to determine how many marbles Paul has.

Given that Dora has x/3 marbles, we can calculate the amount of marbles Paul has:

Paul's marbles = x - Dora's marbles

Substituting in the value of Dora's marbles:

Paul's marbles = x - x/3

Next, we'll need to simplify the expression:

Paul's marbles = (3x - x) / 3

Paul's marbles = 2x / 3

Therefore, the fraction of the marbles that Paul has is 2x/3.

To find the fraction of marbles that Paul has, we need to find the difference between the total number of marbles and the number of marbles Dora has.

Let's start by assigning a value to the variable x, representing the total number of marbles. According to the problem, Dora has x/3 marbles.

So, we can say that the fraction of marbles Paul has is given by:
Paul's marbles = Total marbles - Dora's marbles

Let's substitute the values we have:

Paul's marbles = x - x/3

To simplify this expression, we need a common denominator:

Paul's marbles = 3x/3 - x/3

Now, let's subtract the fractions:

Paul's marbles = (3x - x)/3

Finally, we can simplify the numerator:

Paul's marbles = 2x/3

Therefore, the fraction of marbles that Paul has is 2x/3.
