Answer 2

$\frac{5}{7}$ is the simplest form.

• The fractions with distinct numerators and denominators but the same value are said to be equivalent fractions. For instance, since $\frac{2}{4}$ and $\frac{3}{6}$ both equal the 12, they are identical fractions. An element of a whole is a fraction. The same amount of the whole is represented by equivalent fractions.
• According to equivalent fractions, two or more fractions are considered to be equal if, following simplification, both provide the same fraction. Let's imagine that $\frac{a}{b}$ and $\frac{c}{d}$ are two fractions. If these fractions are simplified to produce comparable fractions, such as $\frac{e}{f}$, they are then equal to one another.

Here, according to the given information, we are given that,

The fraction is $\frac{15}{21}$.

Now, the fraction can be written as,

$\frac{15}{21} =\frac{5.3}{3.7} = \frac{5}{7} .$

Hence, $\frac{5}{7}$ is the simplest form.
