What is 0.98989898 with bar notation

Step-by-step explanation:

We require to create 2 equations with the repeating value (0.989898... )

placed after the decimal point.

let x = 0.989898.... → (1) ( multiply both sides by 100 )

100x = 98.9898..... → (2)

Subtract (1) from (2) thus eliminating the repeating decimal

99x = 98 ( divide both sides by 99 )

x =

Thus

0.989898... = as an exact fraction

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
