Answer 2

Answer

Step by step explanation:

We have to subtract both the fractions

9/10 - 5/7

Both fractions has different denominator

So,we have to find the LCM of both the denominators

LCM = 70

Therefore,

5/7 × 10/10 = 50/70

9/10 × 7/7 = 63/70

Now 63/70 - 50/70 = 13/70

So, 13/70 girls were present on Saturday
