Question

rationalize the denominator of 5by7+2by4 3by3​

Answer 1

Answer:

31/14

Step-by-step explanation:

$\frac{5}{7} + \frac{2}{4} + \frac{3}{3}$

There is nothing to rationalise the denominator here.

Rather, we could find the sum.

5/7 + 1/2 + 1 = (10 + 7 + 14)/14. [ By cross multiplication ]

= 31/14

31 and 14 are co-prime numbers. No common factors other than 1. So the answer would be 31/14
