Multiplying ratios is just like multiplying fractions.
Ex:
5:10 = 5/10
5:10 · 2:20 = 5/10·2/20.
keep 5/10,
simplify 2/20 to 1/10,
multiply 5·1, and 10·10, and the answer is 5/100 or .05
Answer:
Most people think about speech when they think about communication but there are many other ways we can also use to communicate with each other.
- Using equipment e.g. Text message or computer
So you would first divide 1/4 by 2 to get 1/8 and then you would add 1/8 to 1/4 to get 3/8 ,since 1/4 is 2/8. 3/8 is eqivalent to 37.5%

Answer:
(x, y) ⇒ (y, -x)
Step-by-step explanation:
Rotation 90° CW is described by the transformation ...
(x, y) ⇒ (y, -x)
_____
<em>Additional comment</em>
If you consider a point on the x-axis after a 90° CW rotation, you realize it must have been on the y-axis before the rotation. That is, the new x-value is the old y-value.
Similarly, a point on the y-axis after rotation 90° CW must have been on the -x axis before the rotation. The new y-value is the old -x value:
(x, y) ⇒ (y, -x) . . . . . (old coordinates) ⇒ (new coordinates), 90° CW
