Question

product of 2 no. is 1575 and thrir quotient is 9/7 find the no.
please solve this...

Answer 1

ab=1575 a/b =9/7
a=9b/7
consider ab=1575
here substitute the value of a
(9b/7)*b=1575

$9 {b}^{2} = 11025$
${3}^{2} \times {b}^{2} = 11025$
taking square root on both side
3b=√11025
3b=105
b=35
consider equation ab=1575 substitute the value of b
a*35=1575
a=1575/35
a=45

therefore a=45 and b=35
