It is the same process because ratios and fractions are the same. For example, ratio 1 : 3 can be written in the form of fractions as 1/3. Ratio 1 : 4 is fraction 1/4, and so on. So, if you want to find equivalent ratios, you will use the same process as for finding equivalent fractions.
Answer:
Step-by-step explanation:
x decreased by 60% = (1-0.60)x = 0.40x
x increased by 80% = (1+0.80)x = 1.80x
Can you add on. What rational numbers are you referring to?
If something is perpendicular, (in a line) then it creates 4 90 degree angles.
Two on the top, and two on the bottom.
I hope this helps!

The answer would be -0.512
You would get this answer because -0.8 times -0.8 equals 0.64. Positive 0.64 times negative 0.8 would result In -0.512
