Answer:
OR 
Step-by-step explanation:
So first you find the difference between the new cost and the old cost:
450 - 370 = 80
So the increase was 80.
When you write it as a fraction you write the increase ( 80 ) over the starting cost ( 370 ).
Thus the answer becomes 
But you can always reduce it to its lowest terms thus:

1. -1/5>-3/5 because we have like denominators we compare the inputs by the numerators.
2. 3/4 > 5/8 the least common denominator is: 8
Rewriting as equivalent fractions with the LCD:
3/4 = 6/8 5/8 = 5/8
Comparing the numerators of the equivalent fractions we have:
6/8 > 5/8
Answer:
-y=-x
The problem:
y=x then -y=?
Step-by-step explanation:
If y=x, then -y=-x.
Just like if u=9, then -u=-9.
Or, if -m=8, then m=-8.
Answer:
8.84×10 To the power of -1
Step-by-step explanation:
stated number and decimal number is 8.84
goal: find the standard form of that number.
Defenition: (Plagarism Copyrights) The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number).
So 0.884 is 8.84/10
next put the numerator of 10 to 1 - 1/10
mulitiply 8.84 by 1/10-
this, the answer is multiply 8.84 by 10 to the power of -1
which is basically 8.84×10 To the power of -1
