BRAINLIEST TO CORRECT explain the following with specific rules and steps to getting the answer

Answer:
4
Step-by-step explanation:
Convert 1 7/9 into an improper fraction:
Multiply 9 and 1 to get 9
Add 7 to 9 to get 16
The improper fraction is 16/9
Now, we have 16/9 ÷ 4/9
When we are dividing two fractions, we have to reciprocate ONE of the fractions to get the answer.
16/9 • 9/4 is what we get.
Then, we can cancel out the 9's in the numerator and the denominator. This gives us 16/4.
16/4 is a division problem which shows 16 ÷ 4 = 4
Answer:
4
Step-by-step explanation:
firstly,when dividing fractions the fraction at the right side of the equation gets flipped that is the fraction gets changed from 4/9 to 9/4,also both fractions aren't of the same descent,the fraction on the left is mixed,so we convert it to an improper fraction so 1 whole number 7/9 is converted to 16/9...so the question is changed to 16/9×9/4 in which 16 and 9 are the numerators and 9 and 4 are the denominators and when multiplying fractions it's numerator×numerator/denominator/denominator so 16/9×9/4 is equaled to 144/36,which when reduced to lowest terms its "4".
