If anyone can help w/ fractions reducing them to the lowest term

1 answer:

4 0

To reduce fractions to lowest terms, find the biggest number that divides evenly into <u>both</u> the numerator and the denominator. Then divide and your new fraction should be in lowest terms if you used the biggest number. This number is called the Greatest Common Factor of the numerator and denominator.

Example:
5/10 reduces to 1/2 because 5 divides into 5 once and into 10 twice.

12/15 reduces to 4/5 because 3 divides into 12 four times, and into 15 five times.

Question 19 Only, Please show your work.<br><br> Solve the problem.

ankoles [38]

Answer:

$5\sqrt{2}$

Step-by-step explanation:

Draw a diagonal (line segment from one corner to the opposite corner). You'll form two right triangles with the diagonal being the hypotenuse of both triangles.

Use the Pythagorean Theorem: (leg)^2 + (leg)^2 = (hypotenuse)^2.

Let h represent the length of the hypotenuse.

$h^2 = 5^2+5^2\\h^2=25 + 25\\h^2 =50\\h=\sqrt{50}\\h=5\sqrt{2}$

The question is just a bit vague. It should say opposite corners. I'm assuming the question does not mean the length of one side!

Which figure best demonstrates the setup for the box method of finding the area of a triangle

Ivanshal [37]

Hi there! The third option shows us the best setup.

We can find the area of a triangle with the standard formula area = 1/2 * base * height.

To be able to fill in this formula, we need to have a base and a height. We can't easily find a triangle with given base and height, so we must look for another option.

We can also take the area of a square (length × width) and then divide the answer by 2. This is possible when we take the third setup. Hence the third answer is correct.
