The simplest form of the given expression
is 
<u>Solution:</u>
Given, expression is 3 11/12 – 1 4/12 
We have to find the simplest form of the value derived from the given expression.
Now, first let us solve the given equation.

converting mixed fractions to improper fractions.


As there are no common terms to cancel it is in lowest form.
Hence, the lowest form of the given expression is 
Answer:
20kg of $0.89 candy
10kg of $1.10 candy
Step-by-step explanation:
Candy 1 = 0.89 per kg
Candy 2 = 1.10 per kg
Total kilogram, kg = 30
Let candy 1 = x ; candy 2 = (30 - x) ;
0.89x + 1.10(30 - x) = 0.96(30)
0.89x + 33 - 1.10x = 28.8
0.89x - 1.10x = 28.8 - 33
-0.21x = - 4.2
x = 4.2 / 0.21
x = 20
20kg of $0.89 candy
(30 - x) = (30 - 20) = 10kg
10kg of $1.10 candy
4n-40=7(-2n+2)
4n-40=-14n+14
subtract -4n from both sides
-40 = -18n +14
subtract -14 from both sides
-54=-18n
divide both sides by -18
3 = n
In percentage form it is 83.33% repeating, but in dollars it is $50
