To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write 5/8 as a percent, we need to find a fraction equivalent to 5/8 that has a 100 in the denominator. We can do this by setting up a proportion.
= 
<h3 /><h3>8n = 500</h3><h3>÷8 ÷8</h3><h3> n = 62.5%</h3><h3>Therefore, 5/8 is equal to 62.5%.</h3><h3 />
To write a fraction as a decimal, we can simply divide the numerator by the denominator.
5 ÷ 8 = 0.625
Therefore, 5/8 is equal to 0.625.

Answer:
Unpainted surface area = 514.28 cm²
Step-by-step explanation:
Given:
Side of cube = 20 Cm
Radius of circle = 20 / 2 = 10 Cm
Find:
Unpainted surface area
Computation:
Unpainted surface area = Surface area of cube - 6(Area of circle)
Unpainted surface area = 6a² - 6[πr²]
Unpainted surface area = 6[a² - πr²]
Unpainted surface area = 6[20² - π10²]
Unpainted surface area = 6[400 - 314.285714]
Unpainted surface area = 514.28 cm²
Answer:
Grades 6 and 8
Step-by-step explanation:
If the relationship of girls to boys in two different grades are proportional, <u>they must have the same ratio</u>. To tackle this problem, we can find the <u>ratios</u> of genders in each grade and compare them.
Step 1, finding ratios:
Finding ratios is just like <u>simplifying fractions</u>. We will reduce the numbers by their<u> greatest common factors</u>.




<u>Can't be simplified!</u>

Step 2:
Notice how grades 6 and 8 both had a ratio of 3:4. We can conclude that these two grades have a proportional relationship between girls and boys.
