0.23
First we have to think that the symbol
%
=
1
100
so that
23
%
=
23
⋅
(
1
100
)
this is read twenty three percent is equal to twenty three multiplied by one divided by one hundred.
the result is the fraction
23
100
Now, to convert to decimal, simply divide 23 by 100
23
÷
10
=
2.3
and
2.3
÷
10
=
0.23
this is the same as
23
÷
100
=
0.23
You have to subtract 5/4 by 2/3 but in order to do that you must find a common denominator or least common multiple so the least common denominator of 4 and 3 is 12 so you have to multiply 4 by 3 and three by 4 to make both denominators 12 but you have to do the same thing on the top as you did the bottom so:
5/4*3= 15/12 and 2/3*4=8/12
Then 15/12-8/12 is 7/12 so Jim has to run 7/12 more
