What is P percent of X?

The above problem can be written in equation format :

Y = P% * X

What is 25% of 60?

• Y = 25% of 60
• Y = (25/100) *60
• Y = 15

Therefore 25% of 60 is 15

Y is what percent of X?

The above problem can be written in equation format :

Y = P% * X

P% = Y / X

15 is what percentage (5) of 60?

• P% = 15/60
• P% = 0.25
• P  =  0.25 * 100
• P = 25

Therefore 15 is 25% of 60

Y is P% of What?

The above problem can be written in equation format :

Y = P% * X

X = Y / P%

15 is 25% of what?

• X = 15 / 25%
• X = 15 / (25/100)
• X = 15/ 0.25
• X = 15 * 100/25
• X = 15 * 4
• X = 60

Therefore 15 is 25% of 60

What percent (% ) of X is Y?

The above problem can be written in equation format :

P% * X = Y

P% = Y / X

What percentage of 60 is 15?

• P% = 15/60
• P% = 0.25
• P%= 0.25
• P = 0.25 * 100
• P = 25

Therefore 25% of 60 is 15.

P% of What is Y?

The above problem can be written in equation format :

P% * X = Y

X = Y / P%

25% of what number is 15?

• X = 15/25%
• X = 15/0.25
• X = 15 * 100/25
• X = 15 * 4
• X = 60

Therefore 25% of 60 is 15.

P% of X is What?

The above problem can be written in equation format :

P% * X = Y

Y = P% * X

25% of 60 is what?

• Y = 25% * 60
• Y = (25/100) * 60
• Y = 0.25 * 60
• Y = 15

Therefore 25% of 60 is 15.

Y out of What is P%?

The above problem can be written in equation format :

Y/X = P%

X = Y/P%

15 of what is 25%?

• X = 15/25%
• X = 15/0.25
• X = 15 * 100/25
• X = 15 * 4
• X = 60

Therefore 15 of 60 is 25%. (15 out of 60 is 25%)

What out of X is P%?

The above problem can be written in equation format :

Y/X =P%

Y= P% * X

What out 60 is 25%? or What of 60 is 25%?

• Y = 25% * 60
• Y = 25/100 * 60
• Y = 0.25 * 60
• Y = 15

Therefore 15 of 60 is 25%. (15 out of 60 is 25%)

Y out of X is What %?

The above problem can be written in equation format :

Y/X = P%

P% = Y/X

15 out 60 is what percent? or 15 of 60 is what percent?

• P% = 15/60
• P% = 0.25
• P = 0.25 * 100
• P = 25

Therefore 15 of 60 is 25%. (15 out of 60 is 25%)

X plus P% is What?

The way to ask the same question is What is the P percentage increase from X?

The above problem can be written in equation format :

X + X * P% = Y

X (1 + P%) = Y

Y = X * (1 + P%)

20 plus 30% is what? or what is 30% increase from 20?

• Y = 20 * (1 + 30%)
• Y = 20 * (1 + 0.30)
• Y = 20 * 1.30
• Y = 26

There fore 30% increase from 20 is 26  or 20 plus 25% (6 is 25% of 20) is 26

X plus What % is Y?

The way to ask the same question is What is the percentage increase from X to Y?

The above problem can be written in equation format :

X + X * P% = Y

X*P% = Y – X

P% = (Y – X)/X

P% = Y/X – X/X

P% = Y/X -1

20 plus what percentage is 26? or what is percentage increase from 20 to 26?

• P% = 26/20 -1
• P% = 1.3 – 1
• P% = 0.30
• P  = 30%

There fore 30% increase from 20 is 26  or 20 plus 25% (6 is 25% of 20) is 26

Therefore 20 plus 30% is 26. (30% is the increase from 20 to 26)

What plus P% is Y?

The above problem can be written in equation format :

X + X * P% = Y

X (1+P%) = Y

X = Y/(1+P%)

What plus 30% is 26?

• X = 26/(1+30%)
• X = 26/(1+0.30)
• X = 26/1.3
• X = 20

Therefore 20 plus 30% is 26.

X minus P% is What?

The way to ask the same question is What is the P percentage decrease from X?

The above problem can be written in equation format :

X – X * P% = Y

X (1 – P%) = Y

Y = X * (1 – P%)

20 minus 30% is what? or what is 30% decrease from 20?

• Y = 20 * (1 – 30%)
• Y = 20 * (1 – 0.30)
• Y = 20 * 0.7
• Y = 14

There fore 30% decrease from 20 is 14  or 20 minus 30% (6 is 30% of 20) is 14

X minus What % is Y?

The way to ask the same question is What is the percentage decrease from X to Y?

The above problem can be written in equation format :

X – X * P% = Y

X*P% = X – Y

P% = (X – Y)/X

P% = X/X – Y/X

P% = 1 – Y/X

20 minus what percentage is 15? or what is percentage decrease from 20 to 15?

• P% = 1 – 15/20
• P% = 1 – 0.75
• P% = 0.25
• P  = 25%

There fore 25% decrease from 20 is  15 or 20 minus 25% (5 is 25% of 20) is 15

Therefore 20 minus 25% is 15. (25% is the decrease from 20 to 15)

What minus P% is Y?

The above problem can be written in equation format :

X – X * P% = Y

X (1 – P%) = Y

X = Y/(1 – P%)

What minus 30% is 26?

• X = 26/(1 – 30%)
• X = 26/(1 – 0.30)
• X = 26/0.70
• X = 37.14

Therefore 37.14 plus 30% is 26.
