You turn it into a percent by multiplying by 100 because a percent means out of a hundred so that's how you do it. You just multiply the decimal by 100.

$78 for each tire
4,992 divided by 64 is 78
1st number = x
2nd number = 3x
3rd number = 2x-10
x +3x + 2x-10 =92
6x - 10 = 92
6x =102
x = 102/6
x = 17
1st number = 17
2nd number = 17*3 = 51
3rd number = 17 *2 = 34-10 = 24
17 + 51 + 24 = 92
3 numbers are 17, 51 and 24
11=y/6
