Question

how can i help my son on doing fractions finding the equivalent fraction.

Answer 1

Do you have an example of what you want to show him. The complexity of the answer depends on the question.

Answer 2

What grade is he in?

Answer 3

he is in 4th grade

Answer 4

Is he having to add fractions like\[\frac{1}{3}+\frac{2}{5}\]?

Answer 5

it is like this 1/2 = /4

Answer 6

Okay...

Answer 7

If the numerators are related to each other in the sense that one divides the other (here, 2 divides 4), you can illustrate the problem with pictures.

Take two identical strips of paper. Draw a line down the middle of both, and draw a line each in the halves of one of them. If you line the up, he should be able to see that two quarters goes into one half. If he can make a visual link first, he'll be better able to deal with what will happen next (when the numerators don't divide, as in the example I wrote above). This is because, to do the latter type of question, we end up converting each of the numerators into a common one...if he has the visual link, it will be easier for him.
