Answer:

15 percent of 90 hours = 13.5 hours

What is 15% of 90?

Y is 15% of 90

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 15% * 90

Converting percent to decimal:

p = 15%/100 = 0.15

Y = 0.15 * 90

Y = 13.5

Okay, to do this, we need to do the Cross-Product Method. On one side, it will be x/90, and the other side will be 15/100. So, after we multiply 90 by 15, and also multiply 100 by x, out new equation is going to be 100x = 1350. After dividing 1350 by 100, we get 13.5

Answer: 15% of 90 hours is 13.5 hours.
