Question

what do you notice about all fractions that are equivalent to 2? Explain and give an example

Answer 1

The numerator is twice as big as the denominator.

Here are some examples:  10/5  8/4   12/6   20/10  300/150

All of these fractions reduce to just 2. If you look at these fractions, you will see that the numerator is twice as big as the denominator.

Answer 2

A fraction is equivalent to two when the numerator is twice the denominator.

When is a fraction equivalent to two?

Let's define a random fraction as: a/b

Where a and b are two integer numbers, such that b is different than zero.

If that fraction is equivalent to two, then we can write:

a/b = 2

Multiplying both sides by b, we get:

a = 2b

Then a fraction is equivalent to two always that the numerator is the double of the denominator, as we could expect.

Examples of that can be:

• 10/5
• 4/2
• 700/350

Where in the 3 cases, the numerator is twice the denominator.
