Answer:

4 1/10

Step-by-step explanation:

You can take any number, such as 4.1, and write a 1 as the denominator to make it a fraction and keep the same value, like this:

4.1 / 1

To get rid of the decimal point in the numerator, we count the numbers after the decimal in 4.1, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers, and so on.

Therefore, in this case we multiply the numerator and denominator by 10 to get the following fraction:

41 / 10

Then, we need to divide the numerator and denominator by the greatest common divisor (GCD) to simplify the fraction.

The GCD of 41 and 10 is 1. When we divide the numerator and denominator by 1, we get the following:

41 / 10

Therefore, 4.1 as a fraction is as follows:

41 / 10

Bonus: If the answer above is an improper fraction, then we also display the mixed number answer below:

4 1/10

The larger of two numbers is 12 more than the smaller number. If the sum of the two numbers is 74, find the two numbers. Show ho

olya-2409 [2.1K]

Set up two equations.
s + 12 = l , s + l = 74 (these equations represent the problem)

s + (s + 12) = 74 plug in "l" to the second equation.

2s + 12 = 74 combine like terms.

2s + 12 - 12 = 74 - 12 subtract to isolate the variable

2/2s = 62/2 divide to isolate the variable.

s = 31. This means the smaller number is 31.

31 + 12 = 43. since the larger number is 12 more than the smaller, add 12.

l = 43 the larger number has a value of 43.

small number = 31
larger number = 43

hope this helps! :D

Simplify

Answer: $4\sqrt{3}$

Step-by-step explanation:

For this exercise it is important to remember the following:

$i=\sqrt{-1} \\\\i^2=-1$

Given the following expression:

$-2i\sqrt{-12}$

You can notice that the radicand (the number inside the square root) is negative. Therefore, in order to simplify the expression, you need to follow these steps:

1. Replace $\sqrt{-1}$ with $i$ and simplify:
