Is #2/5# the same as #5/8# ?

Answer 1

No

Convert #2/5# and #5/8# to fractions with the same denominator. The least common multiple of #5# and #8# is #40#.
#2/5*8/8=16/40#
#5/8*5/5=25/40#
Clearly, #5/8>2/5#.

No

When #b# and #d# are non-zero:
#a/b=c/d" "# if and only if #" "ad=bc#

In our example:

#2*8 = 16 != 25=5*5#

So:

#2/5 != 5/8#

Answer 3

A sort of cheat way:

#5/8# is bigger so the answer is no

If #2/5# was equal to #5/8# then dividing one into the other will give the answer of 1
Consider #2/5-:5/8#

If the answer is less than 1 then 5/8 is bigger. If the answer is more that 1 the 5/8 is maller.

#2/5-:5/8->2/5xx8/5" "=" "16/25# which is less than 1
So #5/8# is bigger

Answer 4

No, 2/5 is not the same as 5/8. To compare fractions, we can find a common denominator and then compare the numerators.

To compare 2/5 and 5/8, we can find a common denominator, which is 40.

[ \frac{2}{5} = \frac{2 \times 8}{5 \times 8} = \frac{16}{40} ]

[ \frac{5}{8} = \frac{5 \times 5}{8 \times 5} = \frac{25}{40} ]

Now we can see that 16/40 and 25/40 are not equal. Hence, 2/5 is not the same as 5/8.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
