To find:
The difference between the given fractions
Solution:
The difference between 8/9 and 2/7 is 38/63.
We can find the difference by following the given process-
We know that the difference between two fractions can be obtained by subtracting them after making the denominators alike.
To get the same denominator for both the fractions we need to take the LCM of both the denominators.
The given fractions are 8/9 and 2/7.
So, the LCM of 9 and 7=63
The fractions with 63 as the denominator become 56/63 and 18/63.
