The mistake lies in step -(66/5)/(22/5) → -(66/5)(22/5) where he didn't take the reciprocal of the divisor while dividing the two fractions.
The step would have been like this:
-(66/5)/(22/5) = -(66/5)(5/22) = -(3).
What are fractions?A fraction is a portion of a whole or, more broadly, any number of equal pieces.
It is written in the form p/q, read as "p by q", where p is called the numerator and q is called the denominator, and the fraction p/q represents p number of equal parts from q number of equal parts.
Fractions are of two types:
Proper fraction: Where numerator < denominator.Improper fraction: Where numerator > denominator. These fractions are written in mixed form also.How are fractions divided?Fractions are divided by multiplying the dividend by the reciprocal of the divisor
Suppose we are asked to divide a fraction a/b by x/y.
This is written as (a/b) ÷ (x/y) or (a/b)/(x/y), and calculated as:
(a/b)*(y/x).
How to solve the question?In the question, we are informed that last night, the temperature fell from 0°F to Negative 13 and one-fifth °F in 4 and two-fifths hours. Alan calculated the average temperature change per hour.
He followed the following steps:
-(13 1/5)/(4 2/5)
= -(66/5)/(22/5)
= -(66/5)(22/5)
= -(1452/25).
The mistake lies in step -(66/5)/(22/5) → -(66/5)(22/5) where he didn't take the reciprocal of the divisor while dividing the two fractions.
The step would have been like this:
-(66/5)/(22/5) = -(66/5)(5/22) = -(3).

-2(-7n-8)=-39+3n. plz solve and explain the answer
Answer:
n = -5
Step-by-step explanation:
-2(-7n-8)=-39+3n
Distribute
14n +16 = -39 +3n
Subtract 3n from each side
14n -3n +16 = -39 +3n -3n
11n +16 = -39
Subtract 16 from each side
11n +16 -16 = -39 -16
11n = -55
divide by 11
11n /11 = -55/11
n = -5
