Answer:
A
Step-by-step explanation:
Rational numbers have an ending decimal expansion. If you put the other numbers into a calculator you will se that there is just more numbers after the decimal point
So lets just simplify them first
1 batch = 2 3/4 so...
11/4 cups
and you need to make 3 1/2 batch so..
7/2 batch
then you just multiply it...
11/4 x 7/2
=77/8
=9 5/8
so you will need 9 5/8 cups
X = -2
set equations equal and solve
2x+7 = -x+1
collect like terms
3x = -6
divide
x=-2
Answer:2+6+2+1+3+2+1+1+3+0+4+2=27
27 divided by 12=2.25
