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
.
It's easier to see the numbers if you use commas.
6,289,002
The 6 is in the millions place. When rounding, if the following number is 5 or higher, you would round up. If the following number is 4 or less, you would round down. The number following the 6 is a 2, so you would round down. The nearest million would be 6,000,000.
