<h2>Answer:</h2>

The answer is 3/4 or 0.75

<h2>Step-by-step explanation:</h2>

So this is the expression we have

$\frac{\frac{1}{2} }{\frac{3}{4} } \\\\$

Now, let´s simplify the fraction using formula

$\frac{\frac{a}{b} }{\frac{c}{d} }$ = $\frac{a*d}{b*c}$

We get this

$\frac{1*3}{2*2}$

Now, we multiply everything.

We get answer.

The answer is 3/4 which is also 0.75

I hope that I helped you. I will be glad if you mark my answer as the brainliest.

A series contains 18 numbers and has a sum of 4,185. The last number of the series is 275. What is the first number?

N76 [4]

If the series is made up of numbers in an arithmetic progression, you have

$\displaystyle\sum_{n=1}^{18}a_n=\sum_{n=1}^{18}(a_1+(n-1)d)=18a_1+153d=4185$

where $a_1$ is the first term and $d$ is the common difference between terms.

Since the last term in the series is $a_{18}=275$ , you have

$a_{18}=a_1+(18-1)d\implies a_1+17d=275$

Solve the system

$\begin{cases}18a_1+153d=4185\\a_1+17d=275\end{cases}$

and you'll find that the first term is $a_1=190$ (with $d=5$ ).
