$\bf\frac{18}{5} \: or \: \frac{18}{8}$

$\bf{➱ \: L.C.M \: of \: 5 \: and \: 8=40}$

$\bf \frac{18}{5}= \frac{18×8}{5×8}= \frac{144}{40}$

$\bf \frac{18}{8} = \frac{18 \times 5}{8 \times 5} = \frac{90}{40}$

$\bf\frac{144}{40} \: > \frac{90}{40}$

$\bf{∴ \frac{18}{5}> \frac{18}{8}}$

Answer 2

Answer:

The greatest fraction is $\frac{18}{5}$.

Step-by-step explanation:

Given : The fractions are $\frac{18}{5}$ and $\frac{18}{8}$.

To find : The greatest fraction between the given fractions.

Solution :

• The given fractions are, $\frac{18}{5}$ and $\frac{18}{8}$.
• We have to find the greatest fraction between the given fractions.
• To find out the given fractions, use the cross multiplication method.
• In cross multiplication method, cross multiply the given fractions and which ever the fraction is greater.
• Now, the given fractions are,

         $\frac{18}{5}$ and $\frac{18}{8}$  

• By doing cross multiplication, we get

      $18*8=144$

      $18*5=90$

     ∴ $144>90$

     ∴ $\frac{18}{5}$ > $\frac{18}{8}$  

• ∴ The greatest fraction is $\frac{18}{5}$.
