Answer:
7/18
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(5/6, 4/9) = 18
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal to the LCD. This is basically multiplying each fraction by 1.
Complete the multiplication and the equation
The two fractions now have like denominators so you can subtract the numerators.
15/18 −8/ 18 = 7/18
Therefore:
5/6−4/9=7/18
