Question

james and john shared 63 marbles in the ratio 4:5 how manzly marbles did john get

Answer 1

So if the ratio is 4:5, we know that this total amount of marbles must first be split into 9 equal parts:

$\frac{63}{9}=7$

Now we know that each 'part' is going to be equal to 7 marbles.

So then in the ratio, we are simply going to multiply each side by 7:

$4:5=28:35$

Therefore, since John had the part of '5' in the ratio, the amount of marbles that John got was 35.
