60 percent of a number is 66. Which proportion best represents this relationship.

The proportion that best represents the given relationship is 110 and this can be determined by using the unitary method.

Given :

60 percent of a number is 66.

The following steps can be used in order to determine the proportion that best represents the given relationship:

Step 1 - The unitary method can be used in order to determine the proportion that best represents the given relationship.

Step 2 - Let the unknown number be 'a'.

Step 3 - According to the given data, the value of 'a' can be calculated as:

Step 4 - Simplify the above expression.

So, the proportion that best represents the given relationship is 110.

Step-by-step explanation:

If 60% or .60 of a number is 66, then we write and equation to solve for the original number, x.

.6x = 66 Divide each side by .6

.6x/.6 = 66/.6

x = 66/.6

x = 110

as a proportion it would be:

60:100 = 66:110

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
