A circle divided into 6 parts. 1 part is shaded. Which best describes the fraction represented by the shaded portion of the circle?

Since 1 of the 6 equal parts is shaded, the shaded portion represents One-sixth.
Since 1 of the equal parts is shaded and 5 are not shaded, the shaded portion represents One-fifth.
Since 5 of the 6 equal parts are unshaded, the shaded portion represents Five-sixths.
Since 5 of the equal parts are unshaded, the shaded portion represents Five-fifths.

5/6

Step-by-step explanation:

Since 1 of the 6 equal parts is shaded, the shaded portion represents One-sixth.

Since 1 of the equal parts is shaded and 5 are not shaded, the shaded portion represents One-fifth.

Since 5 of the 6 equal parts are unshaded, the shaded portion represents Five-sixths.

Since 5 of the equal parts are unshaded, the shaded portion represents Five-fifths.

1/6

Step-by-step explanation:

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
