0.78

Explanation:

So basically, all you have to do is take the number on top which we called the numerator then we divide it by the number at the bottom which we called the denominator.

So

#25/32= 0.78#

Divide the bottom into the top.

#color(white)(....)#_____
32 )25 = 0.78

Explanation:

Among other things, the fraction bar is also a division sign.

#(25)/(32)# means "25 divided by 32"

#(25) / (32)##larr# "divided by"

So to convert the fraction into a decimal, you divide 25 by 32.

#25 -: 32#

It's always good to know the answer before you begin

First step:
You can tell that the answer is going to be a number smaller than #1# because the numerator isn't large enough. To get one complete "one," you'd have to have all 32 of the pieces.
.........................

Second step: Estimate the answer

#(25)/(32)# is close to #(25)/(30)#

#(25) / (30) # can be reduced to #(5)/(6)#

By memorization, #(1)/(6)# = about #0.17#

So #(5)/(6)# is about #0.83#
...............................

Last step: Do the indicated division
#color(white)(....)#_____
32 )25 = 0.78

........................

Check
The final answer is close to the estimate, so it's probably right.
