the pet shop owner told Jean to fill her new fish tank 3/4 full with water jean filled it 9/12 full.what fraction of the tank does jean still need to fill

Respuesta :

The answer is no more water.

3/4=9/12

3/4
From 3 to 9 it is X3 and from 4 to 12 it is X3.So you take 3*3 which is nine and 4*3 which is 12 and now you have this

9/12=9/12
No more water because since if you multiplied 3/4 by two then it will equal 9/12
