So when ur trying to divide fractions that can't really "happen" for one u may not get the correct answer so u (KCF) which would mean "keep change flip" so this is what u should get
See what we did there? We switch the second fraction and instead of division we did multiplication so then if u multiply across you should get
Then find the greatest common factor which is 2 then divide both of them by two straight across then u would get
Cause 6 divided by 2 =3
And 10 ÷2 =5

Answer: 8.82</h3>
Work Shown:
(5.15)/(6.30) = (7.21)/(x)
5.15*x = 6.30*7.21 ....... cross multiply
5.15x = 45.423
x = (45.423)/(5.15) ...... dividing both sides by 5.15
x = 8.82
