Which fraction shows the ratio 16:200 as a fraction simplified form

svlad2 [7]

Answer:

C. $\frac{2}{25}$

Step-by-step explanation:

We have been given a ratio 16:200 and we are asked to find the ratio as a fraction in simplified form.

Since ratio compares two numbers or two quantities that are measured with the same unit.

Upon converting our ratio into fraction we will get,

$\frac{16}{200}$

Let us cancel out greatest common factor from numerator and denominator of our fraction to simplify it.

$\frac{16}{200}=\frac{8*2}{25*8}$

After cancelling out 8 we will get,

$\frac{2}{25}$

Therefore, our fraction simplifies to $\frac{2}{25}$ and option C is the correct choice.

Please i want to know how to find slope intercepts

algol [13]

Answer:

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.

Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Step-by-step explanation:

The general formula is y = mx +b.

m = slope.

b = y-intercept of the line
