Malachy, gavin and Gavyn share $18 in a ratio 3:1:2 how much money does each person get ?

Malachy- $9
Gavin- $3
Gavyn- $6

Solution;
Add up all the numbers in the ratios. So 3+1+2 is 6. Now do the money ($18) divided by the tattled up ratio (6). 18 divided by 6 is $3 which is now equal to 1. Now for malachy you do his ratio (3) times our number equal to one of those ratios (3). 3 times by 3 is $9. Same for others. 1 times 3 is 3. 2 times 3 is 6.
