The answer is 149/99 cm

GIVEN

Arnav gained 7/9 cm height in 6 month in the next 6 months, he gained another 8/11 cm.

TO FIND

The total height gained by arnav in one year.

SOLUTION

We can simply solve the above problem as follows;

Height of Arnav gained in 6 months = 7/9cm

Height of Arnav gained in another 6 months = 8/11 cm

Total height gained by Arnav = Sum of heights gained by Arnav.

Therefore,

Total height = 7/9 + 8/11

We will make the unlike fractions into like fractions by making taking the lcm of the denominators

LCM of 9 and 11 = 9 × 11 = 99

Therefore,

$= \frac{7 \times 11 + 8 \times 9}{99}$

$= \frac{77 + 72}{99}$

= 149/99 cm

Hence, The answer is 149/99 cm
