Answer 2

Answer:

So the largest number in  $\frac{15}{17} , \frac{15}{18} , \frac{15}{19} ,\frac{15}{21}$. is $\frac{15}{17}$.

Step-by-step explanation:

We need to find the largest number in $\frac{15}{17} , \frac{15}{18} , \frac{15}{19} ,\frac{15}{21}$.

Now we use a trick . Firstly we find the LCM of the denominator. Then we multiply the number with the every fractional numner. Then every fractional number will become a integer number. Then we can easily find out the largest number in  $\frac{15}{17} , \frac{15}{18} , \frac{15}{19} ,\frac{15}{21}$.

LCM of 17 , 18 , 19 , 21 is  40698.

$\frac{15}{17}*40698=2394 , \frac{15}{18}*40698=2261 , \frac{15}{19}*40698=2142 , \frac{15}{21}*40698=1938.$

Largest number is 2394.

So the largest number in  $\frac{15}{17} , \frac{15}{18} , \frac{15}{19} ,\frac{15}{21}$. is $\frac{15}{17}$.
