how do u write these answers in simplest form,12over15,9over24,25over30,21over49,20over36,5over4,18over24,?

Answer 1

I am assuming you are talking about fractions:

12/15, 9/24, 25/30....etc.

You need to find the Greatest Common Divisor (GCD) of the two numbers.

The GCD of 12 and 15 is 3. 3 will go into 12 four times and 3 will go into 15 five times. Thus, 12/15 in simplest form is
4/5. The GCD of 9 and 24 is 3. 3 will go into 9 three times and 3 will go into 24 eight times. Thus, 9/24 in simplest form is 3/8.

I hope this helped.

Answer 2

12/15=3/5, 9/24= 3/8, 25/30=5/6

Answer 3

Here are the answers in simplest form:
I. 12/15=4/5
II. 9/24=3/8
III. 25/30=5/6
IV. 21/49=3/7
V. 20/36=5/9
VI. 5/4=1 1/4
VII. 18/24=3/4

Hope it helps you understand...

Answer 4

12 over 15 would be written as ,4 over 5, because 3 can divide evenly into both numbers...

so find the common denominator

Answer 5

12/15=0.8
9/24=0.375
25/30=0.83333333

Answer 6

ur question is not very clear but if this is what u meant - 0.8, 0.36
