A product of fractions

$\frac{10}{4}$ x $\frac{7}{3}$ = $\frac{70}{12}$ or $\frac{5}{2}$ x $\frac{14}{6}$ = $\frac{70}{12}$ . That means N = 70

it is given that... 5/2 x 7/3 = N/12 THIS IMPLIES THAT 35/6=N/12 NOW WE WILL BE APPLYING THE CONCEPT OF EQUIVALENT FRACTIONS... JUST FOCUS ON THE DENOMINATOR.. IT CAN BE CLEARLY SEEN THAT WHEN THE DENOMINATOR 6 IS MULTIPLIED BY 2 WE GET 12.. SIMILARLY WE WILL MULTIPLY THE NUMERATOR ALSO BY 2.. THAT IS 35 x 2 = 70 hence N=70.. :) :)

It is given that 2 multiplied by 3=12 but 2 multiplied by 3=6 So, 2 multiplied by 3 multiplied by 2=12 Similarly, 5 multiplied by 7 multiplied by 2 =70

nu->5 7=35 de->2 3=6 both are multipied by 2 nu 35 2=70 de 6 2=12 therefore N=70

(5/2) * (7/3) = N/12 (5 7)/(2 3) =N/12 35/6 = N/12 (35/6) 12 = (N/12) 12 (Multiplied by 12 both the sides) 35*2 = N therefore N = 70
