Answer 1

Hey mate

here goes your answer

firstly i will consider the original numerator as x and denominator as y

$\frac{120}{100} \times x = 16 \\x = \frac{160}{12} \\ x = 13.34$

$\frac{90}{100} \times y = 21 \\ y = \frac{210}{9} \\ y = 23.34$

the fraction is

$\frac{13.34}{23.34}$

hope it helps u
