Answer:
Step-by-step explanation:
Firstly, we can simplify the ratio of boys to girls to
1
:
2
.
Then, to find out how many students each ratio represents, we add up
1
and
2
to get
3
(
1
+
2
=
3
).
By dividing
3
by the number of students, we can find how many students ONE ratio represents:
24
3
=
8
.
So ONE ratio is equal to
8
boys. Since our simplified ratio of boys to girls is
1
:
2
already, we do not have to do further multiplying - the number of boys is simply
8
.
For the girls, simply multiply
2
by
8
to get
16
.
Check:
8
boys
+
18
girls
=
24
students
.
Answer:
49.7%
Step-by-step explanation:
A cdircle is located within a square.
<u>Area of the circle</u>
Area = 
, where r = 4 units.
Area Circle = 50.3 units^2
<u>Area of the square</u>
Area = l*w or l^2 for a square, since l = w
Area = (10 units)^2
Area = 100 units^2
<u>Area in the square but outside the circle</u>
This is the difference [Square minus Circle Areas]
Square minus Circle Areas = 100 - 50.3 or <u>49.7 units^2</u>
<u>Probability</u>
The probability of picking a point in the square that is not in the circle is the ration of the two areas: <u>[Outside Circle/Square]x100%</u>
<u></u>
<u>(</u>49.7 units^2)/(100 units^2)x100% = 49.7%
<u></u>
Hi there Moon,
The proportion you’re looking for would be 2/5, it is the smallest possible fraction
