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".

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
