Question is too vague.

Mean to comfusing

Ratio of first quantity to second quantity is constant

- anonymous

It's b then.

- anonymous

when i do it it gives me 2.82857

- anonymous

and alot of wacky numberrs

- nubeer

Ratio
2 : 7
now we make the second side 1 as it's data is given
so divide both sides by 7
2/7 : 1
now for second quantity 9.9 is given
so multiply both sides with 9.9
9.9 * (2/7) : 1 * 9.9
