algebra 4/5-2/3?

Question

I am trying to apply for a job and I forgot my algebra can you guys help me. please..

Answer 1

4/5-2/3 = ( 3*4 - 5*2)/15 = 2/15

Answer 2

First you need common denominators in your question.

so what number can both of these go into? 15.

so you multiply 4/5 by 3/3, so you still have 4/5 but not reduced. You get 12/15. Then you multiply 2/3 by 5/5 and then the answer is 10/15. Then you just subtract 12/15-10/15.

Then you get 2/15! This can't be reduced. So you stop there.

Answer 3

4/5-2/3

remember, the denominators have to be the same. in this case the least common multiple is 15, so multiply 4/5 by 3 so that the denominator, 5 will become 15
12/15
same with 2/3
12/15-10/15

answer 2/15

Answer 4

find the same denominators and how ever many you multiply the first denominator by to get the common denominator you must multiply the top # by (numerator) the same amount example:
4/5
to get 15 with 5 you must multiply 5X3 so you do that to the top to 4X3=12
4/5=12/15
same with 2/3
3X5=15
2X5=10
2/3=10/15

12/15 - 10/15
(12-10=2)

12/15-10/15=2/15 (and it can not be simplified so there is your answer!)

Answer 5

youhave to find the common demoninator. multiply 4/5 times 3/3 and 2/3 time 5/5. this comes out to 12/15-10/15=2/15

Answer 6

LCD : 15
12/15 - 10/15 = 2/15

Answer 7

4/5 - 2/3

15 is your lcd

4/5=12/15
2/3=10/15
--------------
2/15

Answer 8

2/15, or 0.133333333...
