The simplest form of the given expression is
<u>Solution:</u>
Given, expression is 3 11/12 – 1 4/12
We have to find the simplest form of the value derived from the given expression.
Now, first let us solve the given equation.
converting mixed fractions to improper fractions.
As there are no common terms to cancel it is in lowest form.
Hence, the lowest form of the given expression is
Answer:
1) 20%
2) Choice a.
Step-by-step explanation:
1) is the population initially.
is the population after a year.
represents the population increase factor.
So let's evaluate that fraction:
0.2=20%
2) Let's figure out the population growth in terms of months instead of years.
We want t to represent months.
A full year is 12 months, in a full year we have that
So we want a new P such that since 12 months equals a year.
Let's look at the functions given to see which gives us this:
a)
b)
c)
d)
So a is the function we want.
Also another way to look at this:
where
is in years.
where
is in months.
And
