Question

Reduce 18/42
in fraction ​

Answer 1

Answer:

The lowest term of fraction 18 / 42 is 3 / 7

Step-by-step explanation:

To reduce a fraction in lowest term we divide the numerator and denominator with same no.

Here numerator is 18 and denominator is 42 .

18 / 42=( 18 ÷ 2) / (42 ÷ 2)

           = 9 / 21

           = (9 ÷ 3 ) / ( 21 ÷ 3 )

           = 3 / 7

Now, there is no common factor between 3 and 7 so we do not divide it further.

So, the lowest term of fraction 18 / 42 = 3 / 7

Answer 2

Answer:

∴ The reduced form of given fractional number $\frac{18}{42}$ is $\frac{3}{7}$.

Step-by-step explanation:

In context to the question asked,

• We have to reduce the given fractional number $\frac{18}{42}$.
• Here, numerator is $18$ and denominator is $42$.
• We have to the given fraction means we have to divide numerator and denominator both by their common factor.
• As $6$ is a common factor of $18$ and $42$, we can divide the given fraction by $18$.
• Now, the given fraction is,

           $\frac{18}{42}$

• Dividing by $6$ to the numerator and denominator, we get

          $\frac{18}{42}=\frac{3}{7}$  

• ∴ The reduced form of given fractional number $\frac{18}{42}$ is $\frac{3}{7}$.
