132 days to 125.4 days percent of change

Answers

Answer:

132 days to 125.4 days percent of change

Step-by-step explanation:

p= N-O/O x 100% where p is the percent change, is the New value and O is

the Old value. We are given the Old value (132) and the New value (125.4) which we can substitute into the formula to calculate the percent change:

p= 125.4-132/132 x 100%

p= -6.6/132 x 100%

p= (-660/132%)

p= -5%

.05% of change is the answer

Answers

Answer:

+1/-7 = negative irrational

+4/+5 = positive rational

-1/-7 = positive irrational

-4/+5 = negative rational

-1/+7 = negative irrational

+1/+7 = positive irrational

+4/-5 = negative rational

-4/-5 = positive rational

Step-by-step explanation:

so when this problem there is only the fractions 1/7 and 4/5

we know that 1/7 is irrational and 4/5 is a rational this is because 1/7 if you put it in a calculator it has a lot of decimals numbers behind it . you can just memorize this though . 4/5 however is 0.2 which is a rational number . you can do this from long division or put it in a calculator to get 0.2.

now for the positive and negative part of this problem we know that

1) a negative and a negative make a positive

2) a positive and a negative make a negative

3) a positive and a positive make a positive

using these we know that when a fraction has a negative in the denominator you can also put that out front and it will be the fraction as negative . however if there are negatives in both the numerator and the denominator then the fraction is positive because the negatives cancel .

+1/-7 = negative irrational

+4/+5 = positive rational

-1/-7 = positive irrational

-4/+5 = negative rational

-1/+7 = negative irrational

+1/+7 = positive irrational

+4/-5 = negative rational

-4/-5 = positive rational

Answer:

+1/-7 = negative irrational

+4/+5 = positive rational

-1/-7 = positive irrational

-4/+5 = negative rational

-1/+7 = negative irrational

+1/+7 = positive irrational

+4/-5 = negative rational

-4/-5 = positive rational
