Answer:
4/45
Step-by-step explanation:
when dividing fractions, you multiply the first fraction by the second fraction's reciprocal :
1/9 divided by 5/4
1/9 multiplied by 4/5
essentially, you switch the signs from division to multiplication, and reverse the second fraction.
1/9 multiplied by 4/5
1/9*4/5 = 4/45
