Answer:

Step-by-step explanation:
When dividing fractions, the formula is simple: Keep Flip Change (KFC)
So keep
change your division sign to a multiplication sign, and flip
so it becomes
.
·
=
Then you need to reduce your fraction to simplest form.

Answer:
1. 1:2
2. x=12
3. $25:$20
4. 15 cats
5. 16 t
6. p=4
7. $15/6 = 2.50
8. 10/5=2 8/2=4 x=4
8b. 8:10=4:5
9. 270/3=90=1 person 90 x 10=$900
you need $900 to bring 10 people on the fishing trip.

Answer:
Step-by-step explanation:
(8 - 4)/(6 - 2) = 4/4 = 1
y - 4 = x - 2
y = x + 2
Explanation:
Level 2
Part 1: √250 would be simplified to 5√10, because you need to find two factors that equal 250. 25 multiplied by 10 are two factors that you can utilize. Because 25 is a perfect square, it could be reduced to 5. Because 10 isn't a perfect square, you leave it as a radical.
Part 2: √250 is an irrational number because it's a non-terminating decimal and you cannot convert it into a fraction, so it wouldn't be rational.
Level 3
Part 1: √150x^5 would be simplified to 5x^2√6x. Again, find two factors that equal the product, 150. 25 multiplied by 6 are two factors that are useable. Just like the first question, 25 is a perfect square, so it can be reduced to 5. 6 is not a perfect square, so you would leave as a radical. Now, moving onto x^5. You can factor out x^4, because it's a perfect square. x^4 can become x^2. Move x^2 next to 5 and x would be left in the radical with 6.
Part 2: It's rational because 2√4 is simply just 2 x 2 because √4 is a perfect square. 4+7=11. 11 can be converted into a fraction, so it wouldn't be irrational.
Level 4
Part 1: 13√750x*5 y*8 would be simplified to 65x^2y^4√30x. Find two factors that equal 750, which are 25 and 30. You know the drill, 25 is reduced to 5 and 30 stays as a radical. Multiply 13 and 5 to get 65. Factor out x^4 out of x^5 to get x^2. x^8 is a perfect square that can be reduced to x^4.
Part 2: Two unique expressions are 4√16+3 and 5√8 x 34. √16 is a perfect square, so it can become 4. 4 x 4 is 16 and 16 + 3 = 19. 19 is a rational number. 5√8 is irrational, so right off the bat, you'll know it's an irrational expression.
