Question

compare 15/30 and 35/40

Answer 1

By using cross multiplication we can compare fractional numbers
So,
$\frac{15}{30} \times \frac{35}{40} \\ 600 \: and \: 1050$
1050 is greater than 600
So,
$\frac{15}{30} < \frac{35}{40}$

Answer 2

Hey it's Abhinav,

First we will find the LCM of denominators
30,40
That is 120 then we will divide the Lcm with denominators and then we will multiply the quotient with numerator . But the denominators will be the Lcm.

60/120 and 105/120

So now which is greater

It is clear
That 35/40 is greater.
