#12 3/4 = 12.75#

#12 75/100 = 1275/100 = 1275%#

Explanation:

The fact that we are working with a mixed number means we will have a whole number and a decimal.

Let's look at the #3/4# first: There are 2 options:

Divide 3 by 4 to get 0.75.

Or change #3/4# into an equivalent fraction with a power of 10 in the denominator, because this represents a decimal.

#3/4 xx 25/25 = 75/100 = 0.75#

If we include the whole number 12 we have #12 3/4 = 12.75#

#12 75/100 = 1275/100 = 1275%#
