Dividing a whole number and an improper fraction seems tricky, but it just has one or two more steps than the normal process. First, convert the whole number "9" into a fraction by giving it a denominator of "1". It should look like 9/1. Now that both numbers are converted into like formats (improper fractions), you should have 9/1 divided by 5/3.
Second, flip 5/3 over into 3/5 - this is the "reciprocal". Now you have 9/1 divided by 3/5. It's just a matter of multiplying across the math sentence. Multiply the numerators (9x3) and the denominators (1 x 5). Your new fraction should be 27/5. This is your answer in the improper fraction format.
You can create other formats depending on the expected answer. For a mixed number, "divide your fraction UP" (27 divided by 5) which gives you 5 and 2/5. This can be further converted into 5.4 if you need your answer in decimal form.

Answer:
x = ±5sqrt(2)
Step-by-step explanation:
x^2 = 50
Take the square root of each side
sqrt(x^2) = ±sqrt(50)
x = ±sqrt(25*2)
We know that sqrt(ab) = sqrt(a) sqrt(b)
x = ±sqrt(25)*sqrt(2)
x = ±5sqrt(2)
