Answer:
Part a)
Part b) 132:89 vs 132 to 89
Part c)
Part d) 66:7 vs 66 to 7
Step-by-step explanation:
Let
x ----> the number of boys
y ----> the number girls
z ----> the number of adults
we have
x=132, y=89, z=14
Part a) Write the ratio of the number of boys to the number of girls.
To find the ratio of the number of boys to the number of girls, divide the number of boys by the number of girls
so
substitute
Part b) Write the same ratio using another form (A: B vs. A to B)
we have
The other form is
132:89 vs 132 to 89
Part c) Write the ratio of the number of boys to the number of adults
To find the ratio of the number of boys to the number of adults, divide the number of boys by the number of adults
so
substitute
Simplify
Part d) Write the same ratio using another form
The other form is
66:7 vs 66 to 7
