## Equivalent fractions

Equivalent fractions are equal in value, even though they look different.

E.g.: $\;1/2=2/4$

We can draw it:

When we multiply or divide the numerator (the top number) and the denominator (the bottom number) of a fraction by another fraction with the same numerator or denominator, it keeps the same value. A fraction with the same numerator and denominator
is actually equal to 1 and by multiplying or dividing by 1 we won't change the value of original fraction.

E.g.:

If there is a missing part of a fraction in an equation, we need to find the equivalent fraction:

We need to multiply 1 by 2 to get 2. We need to do the same with the denominator (3). And 3×2=6

If there is a missing part of a fraction in an inequality, we need to find the equivalent fraction at first and then decrease/increase it to have it greater or smaller. E.g.:

Since $3/8$ are equivalent to $6/16$, we need to find a fraction that has 6 as a numerator (top number) and at the same time it is smaller than $6/16$. This is any fraction with a denominator greater than 16, e.g. $6/17 ; 6/18 ; 6/19$
