subtract the fractions and write the difference in lowest terms 8/2-3/5?

Question

math sucks

Answer 1

The LCD is 10 so you change 8/2 to 40/10 and you change 3/5 to 6/10, then you subtract those new numerators and get 34 which makes it 34/10 which reduces by 2 to 17/5. As a mix number that would be 3 2/5.

Answer 2

OK, here you have two different denominators. 2 and 5. in order to subtract these fractions both have the have to have a common denominator which means that it has to be the same number in both denominators (bottom).

So we take 2 and 5 and see what number they have in common. The lowest number they have in common would be 10 (2x5).

So we take 8/2 and multiply it by 5/5 so the denominator will be 10.
(8x5 = 40) So we have now instead of 8/2 = 40/10.

Now we do the same thing with the next fraction but we multiply it by 2/2. So we have now instead of 3/5 = 6/10. And now we subtract 40/10 - 6/10 = 34/10 (you only subtract the numerator - top)

Since the question asks for lowest term, we have to simplify 34/10. Usually the first thin I do is ask myself how many times does the denominator (10) fit in the numerator (34). The answer would be 3 (10x3 = 30 and we have 4 left) So now we have 3 4/10.

By looking at the 4/10 part of the fraction you can see that 4 and 10 have a number in common which would be 2. (the 4 can be divided by 2 and so can the 10) So now we have the final answer which is 3 2/5 (4/2 = 2 and 10/2 = 5 which gives 2/5)

Final Answer: 3 2/5

Answer 3

13/18 - 4/9 = so as to subtract fractions the lowest (denominator - d for down) must be the comparable. The 9 can get replaced to make it an 18 via multiplying it via 2. yet once you multiply the lowest of a huge decision you should multiply the desirable suited (numerator) via the comparable huge style. you will multiply the fraction 4/9 via 2/2 the reason the desirable suited and backside ought to be the comparable is two/2 = a million. you fairly have the comparable fraction you basically accelerated it via a fraction that equals a million. So the 4/9 now equals 8/18 even though it extremely is in fact nevertheless the comparable fee....basically could be decreased to 4/9. 13/18 - 4/9 * 2/2 = observe: while multiplying fractions multiply on the instant for the duration of desirable suited and backside 13/18 - 4*2 / 9*2 = 13/18 - 8/18 = observe: while including/subtracting fractions the lowest maintains to be the comparable (they ought to tournament) and the desirable suited ameliorations. 13 -8 / 18 = 5/8 i recognize this grow to be extremely over defined. yet once you print this it could help you with fractions.

Answer 4

8/2-3/5=40/10-6/10=34/10=17/5 or 3 2/5

Answer 5

Cross multiply it take denominators and get common factor 10 so it will be( 40-6)/10=34/10=17/5 or 3. 2/5

Answer 6

40/10-6/10=34/10=3 4/10or 3 2/5

Answer 7

8/2-3/5 = 40-6/10 = 34/10 = 17/5 = 3.4

Answer 8

40/10 - 6/10= 34/10= 17/10 or 1 7/10
