Answer:
Question 1: y-11x+5 I think; Question 2: I'm not sure
Step-by-step explanation:

As, 

=0.301029+0.845098+1.13943
=2.26007
=2.260(approximate)
Answer:
a*b = 1/2
a/ b = 8/9
Step-by-step explanation:
a = 0.66666 and b = 0.75
To multiply it we write the decimal numbers in fraction form
a= 0.666666...
Multiply by 10 on both sides
10 a = 6.66666...
a = 0.66666...
Subtract the second equation
9a = 6
divide by 9 on both sides

so 0.6666 = 2/3
Now we convert 0.75 into fraction form

Multiply top and bottom by 100 to remove decimal

so 0.75 is 3/4
a= 2/3 and b = 3/4


The answer I think is 2. 150/7 is 21 R 3. 296/7 is 42 R 2.
