Determine the growth factor corresponding to 1% increase

For an increase of percentage, it is a growth factor.

For a decrease of percentage, it is a decay factor.

The growth factor is = (1+r)

The decay factor is= (1-r)

As it is increase of 1%, it is a growth factor.

Here the rate of increase is 1% = 1/100 = 0.01

Hence the growth factor is 1 + 0.01 = 1.01

The growth factor corresponding to 1% increase is 1.01.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
