The Ratio of boys to girls at a middle school is 3:2. If the school has 400 people how many will be boys?

2 answers:

5 0

You have to divide 400 by 5. That will equal 80. Since the ratio is 3:2 Just multiply 3 by 80 then 2 by 80! :-)

You can check it by simplifying it again.

240 people are boys
1.You have to find the total of boys and girls there are by adding 3 with 2. (5)
2. You have to divide 400 by 5. (80)
3. You have to multiply 80 by 3 to get the amount of boys there are in 400 people. (240)

Answer:

$\frac{x - 10}{8}$

Step-by-step explanation:

$\frac{3x}{8} - \frac{x + 5}{4}$

The common denominator of both fractions is 8. Therefore,, divide the denominator of each fraction, then multiply what you get by the numerator of each fraction.

Thus:

$\frac{1(3x) - 2(x + 5)}{8}$

$\frac{3x - 2x - 10}{8}$

$\frac{x - 10}{8}$

268 gallons are remaining. The equation would be y=324-7x, with x being 8. 7(8) is 56, and then you take away 56 from 324, which then gives you 268 gallons remaining
