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%

Christina has a garden with 50 flowers in it. The ratios of roses to daisies is 1:4. How many roses does he have? How many daisi
antiseptic1488 [7]
Number of flowers in the garden of Christina = 50
The ration of roses to daisies in Christina's garden = 1:4
Let us assume the common ratio to be = x
Then
x + 4x = 50
5x = 50
x = 50/5
   = 10
Then
Number of roses in the garden of Christina = 1 * 10
                                                                      = 10
Number of daisies in the garden of Christina = 4 * 10
                                                                       = 40
So the number of roses in the garden of Christina is 10 and the number of daisies is 40.

Andrews [41]

Answer:

Step-by-step explanation:

a(x - b) + bx + c  = a

ax - ab + bx + c = a

ax + bx - ab + c = a

x(a + b) - ab + c = a

x (a +b)  = a + ab -c

x=\frac{a+ab -c}{(a+b)}
