Answer 2

Answer:

∴ The fraction $\frac{4}{9}$ is less than $\frac{7}{8}$.  

Step-by-step explanation:

• In context to question asked,
• We have to compare the given fractions, $\frac{4}{9}$ and $\frac{7}{8}$.
• To compare the given fractions, we will use cross multiplication method.
• So, the given fractions are,

       $\frac{4}{9}$ and $\frac{7}{8}$

• By cross multiplication, we get

       $4 \times 8$ and $9 \times 7$

       ∴ $32$  and  $63$

          ∴ $32<63$

          ∴ $\frac{4}{9}$  <  $\frac{7}{8}$  

• ∴ The fraction $\frac{4}{9}$ is less than $\frac{7}{8}$.
