The correct answer is 28.3.

You take 22/1.4 and get 15.7142857143. Then you take 15.7142857143*1.8 which equals 28.2857142857 so you round it up to 28.3 which is the answer.

I hope this helps you:)

The ratio of the number of boys to the number of girls in a school is 5:7.If there are 600 students in the school,how many girls
nekit [7.7K]
So,

The secret to solving problems with ratios is to find the value of one unit.

5:7 = 12 units total

To find one unit, divide the total number of students by the total number of units.
600/12 = a

Simplify
50/1 = a
50 = a

The value of each unit is 50.

Now, multiply the units by the numbers in the ratio.
50(5) = b
250 = boys

50(7) = x
350 = x

There are 350 girls.

Answer:

Never

Step-by-step explanation:

Using the formula to find the sum of the interior angles, (n-2) * 180, we can work backwards.

300/180 +2 = 11/3 or 3.666. Polygons cannot have decimal sides therefore your answer is never.
