Which amount is larger and by how much? A positive number a or the same number a increased by 50% and then decreased by 50% of the result. Also the generator thing said 33 1/3 was wrong.

Step-by-step explanation:

a((100+50)/100)(100-50)/100

a(1.5)(.5)=0.75a

So a is larger than a(1.5)(0.5)

How much larger is a than 3a/4?

a/(3a/4)

a(4/3a)

a is 4/3 greater, so it does indicate a 33(1/3)% increase. Maybe they just want the fraction saying it is 1/3 greater or the difference of 0.25a

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
