i need some help with some fractions for my sis homework . . . .

[lcw1995]

im not good with that stuff.
the questions are:

1. 1/4+2/3=

2. 4/5+2/10=

3. 9/10-1/2=

4. 1/4-3/16=



i got:

1. 11/12
2.10/10=1
3.4/10=1/5
4.1/16=1/2

1. Right
2. Right
3. Right - same as 4 (EDIT - because Dunkopf is right (as usual)

4. Right, but then you reduced it? Had it right at first

Looks great to me except for the last one, which should stay 1/16. The only way it would be 1/2 is if your original value was 8/16 not 1/16. Otherwise...great job!!

so r u sure i had it right at first. i think that you have to reduce them to simplest form?

Fractions are the bane of my life. I have to admit that anything hard than what you are doing, and I just give up. I can do decimals till the cows come home, but fractions just confuse me.

#3 should be 2/5 which is 4/10ths reduced.

Yup. 1/16 = 0.0625 and 1/2= 0.5

1/16 is not equal to 1/2

1/4-3/16 = .25 - 0.1875 = 0.0625 = 1/16

 

[lcw1995]

1. 11/12
2. 10/10 or 1
3. 2/5
4. 1/16

just makin sure

 

[Dunkopf]

#3 should be 2/5 which is 4/10ths reduced.

#2 should be 1

#4 should be 1/16th as someone else said.

Looks like you got the basic concept down. Just double check it and pay attention to details.

And Dunkopf is right...we didn't reduce 4/10...this should be 2/5.
