The ratio of girls to boys at soccer practice is 3:4. If on Saturday there will be a total of 42 players, how many boys will be

Alex777 [14]

Answer:

$Boys = 24$

$Girls = 18$

Step-by-step explanation:

Given

$G:B= 3:4$

$Total = 42$

Required

Determine the number of boys and girls

We have to convert the ratio to fraction;

Number of girls can be calculated as:

$Girls = \frac{G}{G + B} * Total$

$Girls = \frac{3}{3 + 4} * 42$

$Girls = \frac{3}{7} * 42$

$Girls = 3 * 6$

$Girls = 18$

$Boys = Total - Girls$

$Boys = 42 - 18$

$Boys = 24$

Sophia uses 18 beads to make a necklace. Three sixths of the beads are purple. How many beads are purple?

joja [24]

Answer:

9 beads are purple

Step-by-step explanation:

we know that

To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple

$18(\frac{3}{6})=9\ beads$

therefore

9 beads are purple

Another way to solve the problem is convert the fraction in percentage

we have

$\frac{3}{6}=\frac{1}{2}=0.50*100=50\%$

If the total are 18 beads

50% is 9 beads

therefore

9 beads are purple
