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

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".

step-by-step explanation:

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
