what

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.

thx
anonymous
  • anonymous
you're welcome.

  • anonymous
what would the answer be (i suck at math)
anonymous
  • anonymous
how old are you?
anonymous
  • anonymous
why
anonymous
  • anonymous
i want to see if you are old enough to do simple addition and subtraction.
anonymous
  • anonymous
to be safe, what grade are you in?
anonymous
  • 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
  • anonymous
i only in 6 th but i'm in home schooling so my teachers don't help me
anonymous
  • anonymous
what numbers do you have so far?
anonymous
  • anonymous
i have 25/8 and it might be wrong but like i said i suck at math
anonymous
  • 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
  • anonymous
yes
anonymous
  • 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
?
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
  • anonymous
you can divide it by 40
anonymous
  • anonymous
close. do you mean like this 5/40?
anonymous
  • anonymous
actually i was thinking the other way around 40/5
anonymous
  • 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
  • anonymous
yeah thx so much
anonymous
  • anonymous
ok. I'll tell you if your answer is right once you tell me what you get.
anonymous
  • anonymous
do you have an answer yet?
anonymous
  • anonymous
yeah i tried writing it out and it got me i don't know how but it was 1.875
anonymous
  • anonymous
yes. that is exactly correct. good job!
anonymous
  • anonymous
oh um wow i thought i was wrong thx
anonymous
  • anonymous
glad I could be of assistance.
