what

- anonymous

If she ran 1 1/8 miles(equals 9/8) and then 2 miles(equlas 16/8), add them together and subtract them from the distance she need to run.

- anonymous

thx

- anonymous

you're welcome.

- anonymous

what would the answer be (i suck at math)

- anonymous

how old are you?

- anonymous

why

- anonymous

i want to see if you are old enough to do simple addition and subtraction.

- anonymous

to be safe, what grade are you in?

- anonymous

i am and i did the adding it's just your talking about subtracting a fraction from a whole number and i really really really really at math

- anonymous

i only in 6 th but i'm in home schooling so my teachers don't help me

- anonymous

what numbers do you have so far?

- anonymous

i have 25/8 and it might be wrong but like i said i suck at math

- anonymous

that is right so far.
now, in order to add fractions, the denominators, the number at the bottom, must be equal. Did you know that?

- anonymous

yes

- anonymous

good. so you need to find a number that, if you divide it by 8, you get 5. what number is this?

- anonymous

?

- anonymous

think about it like this.
you are addding 25/8 +5, but you can't do it yet because the denominators are not the same.
so what can you do to 5 to let it have a denominator of 8?

- anonymous

you can divide it by 40

- anonymous

close. do you mean like this 5/40?

- anonymous

actually i was thinking the other way around 40/5

- anonymous

right!:) good job.
ok. i made a mistake earlier when I said you are adding 25/8 +5. really, you are doing this:
5-25/8.
Can you take it from here?

- anonymous

yeah thx so much

- anonymous

ok. I'll tell you if your answer is right once you tell me what you get.

- anonymous

do you have an answer yet?

- anonymous

yeah i tried writing it out and it got me i don't know how but it was 1.875

- anonymous

yes. that is exactly correct. good job!

- anonymous

oh um wow i thought i was wrong thx

- anonymous

glad I could be of assistance.
