11. 1 1/2

12.  3/10

Step-by-step explanation:

11.

=1 1/2

Solution by separating parts

Rewriting our equation with parts separated

=3+2/5−1−9/10

Solving the whole number parts

3−1=2

Solving the fraction parts

2/5−9/10=?

Find the LCD of 2/5 and 9/10 and rewrite to solve with the equivalent fractions.

LCD = 10

4/10−9/10=−5/10

Reducing the fraction part, 5/10,

−5/10=−1/2

Combining the whole and fraction parts

2−1/2=1 1/2

12:

=3/10

Solution by separating parts

Solving the fraction parts

9/10−3/5=?

Find the LCD of 9/10 and 3/5 and rewrite to solve with the equivalent fractions.

LCD = 10

9/10−6/10=3/10

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
