Explain using words or drawings how to to write 6/9 in simplest formif you help i will follow you.

Answers

To reduce down a fraction you can try to find factors that go in both the numerator (top # of fraction) and denominator (bottom #)

So, for 6/9, 3 goes in both of them. When you divide each number by 3 you get:

2/3

Hi there!

I can't post a drawing for this, but I will try to explain using my own words on what 6/9 is in it's simplest form.

The number three can go into 6 and 9. Three goes into 6 twice, and it goes into 9 three times.

So our simplified answer is 2/3.
In decimal form this is 0.66666667 (repeating decimal but rounded off to 0.6667)

Question 2: Quadrilateral WXYZ is inscribed in a circle with m∠W = 50° and m∠X = 108°.

What is m∠Y?

Answers

Answer:

For Question 1

$\angle Z =72$ °

For Question 2

$\angle Y =130$ °

Step-by-step explanation:

Given

$\angle X =108$ °

$\angle W =50$ °

For a Quadrilateral inscribed in a circle we have opposite angles are Supplementary that is

For question 1

$\angle X + \angle Z = 180\n108 + \angle Z =180\n\angle Z =180-108=72$

For question 2

$\angle W + \angle Y = 180\n50 + \angle Y =180\n\angle Y =180-50=130$

Answer:

1. 72

2. 130
