80÷12 Show all the work.

answer:

How to reduce (simplify) to lowest terms ordinary (common) math fraction 80/12?

To reduce a fraction, divide both its numerator and denominator by their greatest common factor, GCF.

Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd.

Integer numbers prime factorization:

80 = 24 × 5;

12 = 22 × 3;

Multiply all the common prime factors, by the lowest exponents.

gcf, hcf, gcd (80; 12) = 22 = 4;

Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd

Divide both the numerator and the denominator by their greatest common factor.

80/12 =

(24 × 5)/(22 × 3) =

((24 × 5) ÷ 22) / ((22 × 3) ÷ 22) =

(22 × 5)/3 =

20/3

An improper fraction (numerator larger than denominator), rewrite:

As a mixed number (mixed fraction):

A mixed number (mixed fraction) = a whole number and a proper fraction, of the same sign.

A proper fraction = numerator smaller than denominator.

20 ÷ 3 = 6 and remainder = 2 =>

20 = 6 × 3 + 2 =>

20/3 =

(6 × 3 + 2) / 3 =

6 + 2/3 =

6 2/3

As a decimal number:

6 2/3 =

6 + 2/3 =

6 + 2 ÷ 3 =

6.666666666667 ≈

6.67

As a percentage:

6.666666666667 =

6.666666666667 × 100/100 =

666.666666666667/100 =

666.666666666667% ≈

666.67%
