Answer:

#3/4=0.75#

Explanation:

Divide #3# by #4# to get #0.75#

The division in this case is a bit tricky due to the fact that you have to divide something small #3# into something bigger #4#.

as you can see at the start we borrow a zero to make our #3# into a #30# but we have to "signal" this loan by adding a #0,# into the result; then we take another zero (in red) to form a #20# and finish our division.

Answer:

Here is another method.

Explanation:

#3/4# can be converted to a fraction #x/100#.

How? In the denominator, #4xx\color(red)(25)=100#. So we do the same for the numerator:
#3/4\color(red)((xx25)/(xx25))=(3xx25)/100=\color(blue)(75)/100#

Dividing by 100 means you move the decimal point backwards two digit spaces. So from the numerator value #75.00# you move two back, and you have #0.7500# or #0.75#.

(the 0's are there so you can see the decimal point. They actually don't count)
