Answer:

b = 1

Step-by-step explanation:

8 = b - 1 + 8b

<em>combine like terms</em>

8 = 9b - 1

<em>add 1 to both sides of the equation</em>

<em>8 + 1 = 9b - 1 + 1</em>

<em>8 + 1 = 9b</em>

9 = 9b

<em>divide both sides of the equation by 9</em>

9/9 = 9b/9

1 = b

At book fair, the ratio of adults to children is 7 : 3
joja [24]

The percentage of the boys at the book fair is 6%

<h3>What is a percentage?</h3>

Percentages are used in mathematics as a decimal ratio expressed in a fraction of 100. It is represented with a symbol known as %.

At a book fair, the ratio of adults to children are:

7 : 3

The total number of people at the book fair = 7 + 3 = 10

The percentage of adults are:

\mathbf{=\dfrac{7}{10}\times 100\%}

= 70% are adults

The percentage of children are:

 \mathbf{=\dfrac{3}{10}\times 100\%}

= 30% are children

However, if from the children, 4 are girls and 1 is a boy.

The total number of children at the fair  = 4 + 1 = 5

The percentage of girls are:

\mathbf{=\dfrac{4}{5} \times 30\%}

= 24%

The percentage of boys at the book fair is:

\mathbf{=\dfrac{1}{5} \times 30\%}

= 6%
