Answer:
33.3%
Step-by-step explanation:
(279,000 - 186,000) / 279,000 = 0.33333333333
0.33333333333*100= 33.3333333333
Formula used:
/
× 100
V2= 279,000
V1= 186,000
In order to divide integers, the first thing to check is the sign:
- When dividing two positive integers, the result will be a positive integer.
- When dividing two negative integers, the result will be a positive integer.
- When dividing integers with different signs (one negative and one positive), the result will be a negative integer.
Then, after checking the sign, we need to calculate the value of the division.
Some examples of divisions are:
In the first division, the result is 3, because we have that 8 * 3 is equal 24.
Also, both numbers are positive, so the result is also a positive number.
In the second division, the result is -3, because 5 * (-3) is equal -15.
The result is negative, because the two numbers have different signs.
In the third division, the result is 10, because -10 * 10 is equal -100.
The result is positive, because both numbers are negative.
