6th grade math question - got a headache. . .

[episodic]

Ok shortest solution wins:

Count from 15 to 24

Using nothing but multiplication and division.

Whole numbers. . .

 

[Mo0o]

im assuming whole numbers only?

 

[tweakmm]

15 * 1.6

 

[KLin]

15*4/10*12/3

??

 

[sponge008]

muptiply by 24, divide by 15?

I have no clue what you're asking.

 

[Stiffe]

15 * 2 = 30

30/5 = 6
6*4 = 24

Klin got it - see his response. . .

Stiffe got it too - looking for more ways. . .


Klin 4 steps
Stiffe 3 steps. . .

My son has an outstanding math teacher - this is the kind of stuff she assigns for homework. . .gives me a headache - whatever happened to 303x42?

 

[Ricemarine]

15 / 5 = 3
3*8 = 24

 

[SlitheryDee]

15*16/10

Rice and Klin pratically tied for 2 steps. . .

 

[episodic]

15/(5n)*(8n) = 24 for all non-zero integers n

 

[episodic]

b0mbrman for the most elegant and complicated answer

 

[Ronstang]

15/5 = 3
3*8 = 24

Oops, sorry. This is the answer that popped into my head immediately and I just posted without reading any responses so I did not realize it had already been given.
