compare < > =
1) - 1/7 -6/7
i got : <
2) -3/4 -3/8
i got: <
3) - 1/2 - 2/10
i got : >
4) - 3/4 -1
i got: <
5) - 1/2 - 5/6
i got: <
6) -4/5 -1/3
i got: >
7) 5.2 > -8.3
8) -6.5 > 6.2
9) -4.9 > -4.3
10) 1.09 < -1.90
11) -1.22 < -6.5
12) -10.2 < -10.23
are these correct?
#2 is 3/4 > 3/8
so all but #2 is wrong i see what i did now on # 2 and agree should be <
as:
-3/4 becomes -0.75
-3/8 becomes -0.375
so -0.75 < -0.375
right?
im really confused because i posted this question earlier and someone else just replied and said all my answers are wrong. so now im confused if im right or wrong?
opps sorry i did it again
it should be - 3/4 > -3/8
so i do have them all wrong?
From your above ....
opps sorry i did it again
it should be - 3/4 > -3/8
NO!
Your way, (the way your teacher showed you)
-3/4 = -.75
-3/8 = -.375
Now which is farthest to the right, that is the larger, so
-.375 > -.75 or -3/8 > -3/4
My way, the way I showed you in the other post
3/4 ....... 3/8
3/4 > 3/8
-3/4 < - 3/8
I havent looked at all of them yet, give me a minute and I will, but you definitely don't have them all wrong.
i had < originally for
- 3/4 < - 3/8 you said wrong
but reiny corrected me said
it is: - 3/4 < - 3/8
im missed class yesterday so i will go in tomorrw early
are numbers 6-12 negative number?
no they are mixed
To compare fractions and decimals, you can follow these steps:
1) Compare the whole numbers (if any). If one number has a greater whole number portion, then that number is greater. For example, -6 is less than -1.
2) If the whole numbers are the same, compare the fractions or decimal portions.
For fractions:
- Find a common denominator for the fractions.
- Compare the numerators.
For decimals:
- Compare the digits one by one from the left to the right. The first digit that is different determines the comparison.
Now let's go through each comparison you provided:
1) -1/7 - 6/7:
Both fractions have the same denominator, so you compare the numerators.
-1 is less than -6, so the answer is "<".
Your answer is correct.
2) -3/4 - 3/8:
Both fractions have different denominators, so find a common denominator.
The least common multiple of 4 and 8 is 8, so convert both fractions to eighths.
-6/8 - 3/8 = -9/8
-9/8 is less than 0, so the answer is "<".
Your answer is correct.
3) -1/2 - 2/10:
Both fractions have different denominators, so find a common denominator.
The least common multiple of 2 and 10 is 10, so convert both fractions to tenths.
-5/10 - 1/10 = -6/10 = -3/5
-3/5 is less than 0, so the answer is ">".
Your answer is incorrect. It should be "<" because -1/2 is less than -2/10.
4) -3/4 - 1:
Since 1 can be represented as 4/4, you can convert the subtraction into a fraction.
-3/4 - 4/4 = -7/4
-7/4 is less than 0, so the answer is "<".
Your answer is correct.
5) -1/2 - 5/6:
Both fractions have different denominators, so find a common denominator.
The least common multiple of 2 and 6 is 6, so convert both fractions to sixths.
-3/6 - 5/6 = -8/6 = -4/3
-4/3 is less than 0, so the answer is "<".
Your answer is correct.
6) -4/5 - 1/3:
Both fractions have different denominators, so find a common denominator.
The least common multiple of 5 and 3 is 15, so convert both fractions to fifteenths.
-12/15 - 5/15 = -17/15
-17/15 is less than 0, so the answer is ">".
Your answer is incorrect. It should be "<" because -4/5 is less than -1/3.
7) 5.2 > -8.3:
Since both numbers are decimals, compare them digit by digit.
5.2 is greater than -8.3, so the answer is ">".
Your answer is correct.
8) -6.5 > 6.2:
Since both numbers are decimals, compare them digit by digit.
-6.5 is less than 6.2, so the answer is "<".
Your answer is correct.
9) -4.9 > -4.3:
Since both numbers are decimals, compare them digit by digit.
-4.9 is less than -4.3, so the answer is "<".
Your answer is correct.
10) 1.09 < -1.90:
Since both numbers are decimals, compare them digit by digit.
1.09 is greater than -1.90, so the answer is ">".
Your answer is incorrect. It should be "<" because 1.09 is less than -1.90.
11) -1.22 < -6.5:
Since both numbers are decimals, compare them digit by digit.
-1.22 is greater than -6.5, so the answer is ">".
Your answer is incorrect. It should be "<" because -1.22 is less than -6.5.
12) -10.2 < -10.23:
Since both numbers are decimals, compare them digit by digit.
-10.2 is greater than -10.23, so the answer is ">".
Your answer is incorrect. It should be "<" because -10.2 is less than -10.23.
In summary, the correct comparisons are:
1) < 2) < 3) < 4) < 5) < 6) < 7) > 8) < 9) < 10) < 11) < 12) <
