Answer:5/9
Explanation:
5/4 ➗ 9/4
The division sign would change to multiplication,and the numerator and denominator in the right hand fraction would be inverted
5/4 x 4/9
Multiply both fractions
(5x4)/(4x9)
20/36
Reduce the fraction to the lowest term by dividing both numerator and denominator by 4
(20 ➗ 4)/(36 ➗ 4)=5/9
