Question

please give me solution

Answer 1

The answer is 1, Cancel the terms of numerator and denominator, 5 cancels out 15 leaving 3 in denominator , 3 cancels out another three and leaver 9 *28 in numerator,

7 cancels out 28 leaving 4 *9 in numerator, 4 cancels out 8 in denominator leaving 2 in denominator,

Now we are left with (9/2) ÷ 9/2,

Which is 1, as both are same !


Hope you understand !!

140×9/35×8= 1260/2440×2/9= 252/2196=126/1098=63/549=7/61
