Suppose an amount increases by 100%, then decreases by 100%. Find the final amount. Would the situation change if the original i
Anarel [89]
Well to solve this, lets plug in some numbers. Lets assume that for now, the starting number is 2. If it increases by 100%, bringing it up to 4, then decreases 100%, it is brought down to zero. Now one thing to note is that any number decrease by 100% is automatically zero. Watch, we start with two, it is then increased by 150%, bringing it up to 5, then decreased by 100%, bringing it back down to zero. In conclusion, 100% cannot be specified as a value, but rather a relation. 100% represents the entire number, meaning that if you are decreasing a number by 100%, you are basically subtracting the number by itself!

Is the decimal form of 13/3 a rational number? explain ​

For example, the number 8 is a rational number because it results when the integer 24 is divided by the integer 3, as in the ratio 24/3.
