Answer 2

To solve the expression 17/20 + 1/9 + 5/12, we need to find a common denominator for the fractions and then add them together.

Finding a Common Denominator

The denominators of the fractions are 20, 9, and 12. To find a common denominator, we need to find the least common multiple (LCM) of these numbers.

The LCM of 20, 9, and 12 is 180. Therefore, we can rewrite the fractions with the common denominator of 180:

17/20 = (17/20) * (9/9) = 153/180 1/9 = (1/9) * (20/20) = 20/180 5/12 = (5/12) * (15/15) = 75/180

Adding the Fractions

Now that we have the fractions with a common denominator, we can add them together:

(153/180) + (20/180) + (75/180) = (153 + 20 + 75) / 180 = 248/180

Simplifying the Fraction

To simplify the fraction 248/180, we can divide both the numerator and denominator by their greatest common divisor (GCD). The GCD of 248 and 180 is 4.

248/4 = 62 180/4 = 45

Therefore, the simplified fraction is 62/45.

So, the result of the expression 17/20 + 1/9 + 5/12 is 62/45.
