So i need some help about percentages.
Give a step by step pls.

SO what is 20% of 60

Kind of help me learn about percentages along the way:)

20% of 60 is 12.

Step-by-step explanation:

First Method ;

20% of 60 = 20/100 x 60

                 = 12

Second Method :

1% of 60 = 60/100

              = 0.6

20% of 60 = 1% of 60 x 20

                 = 0.6 x 20

                 = 12

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
