1/8 = 1/8 - you're set for the first one. 3/4 x 2/2 = 6/8 - all I did there was multiply the fraction by '1' only in the form of '2/2.' 1/8 - 6/8 Just subtract the numerators. -5/8 -- ANSWER. Hope this helped, and good luck!! :)

@Tal_Tal An important part of solving a math problem is getting an answer that makes sense. The problem states that a person added an amount of sugar to a bowl. Then some sugar was removed from the bowl. You can end up with some sugar or no sugar in the bowl, but your answer of a negative amount makes no sense because it has no meaning in the real world. That means your answer cannot be correct.

@abby1012 I'm trying to understand the problem. At first, 3/4 cup of sugar was added to the bowl, right?
Tal_Tal
  • Tal_Tal
Thank you for pointing that out I'll keep that in mind next time!

yes @mathstudent55 but it has because and then it has numbers sorry cant copy and paste

3/4 cup was added to the bowl. The 2 amounts of 1/8 cup each were taken from the bowl. Is this what the problem is telling you?
mathstudent55
  • mathstudent55
@abby1012 It's ok. That's why I'm asking to make sure I understand the problem before I try to help you.

Since we are subtracting fractions, we need a common denominator. The LCD of 4 and 8 is 8, so we will use a common denominator of 8 for all 3 fractions.

@abby1012 Do you follow so far?

yip i am still folowing
mathstudent55

When we subtract fractions, we subtract the numerators and just keep the common denominator.

  • anonymous
it is equal 4
mathstudent55
  • mathstudent55
Correct. 6 - 1 - 1 = 4, so our numerator is now 4. The denominator is 8, so we have 4/8
anonymous
  • anonymous
yip i see four over 8 on my multiple choice
anonymous
  • anonymous
thanks i get it
mathstudent55
  • mathstudent55
Since we now have 4/8, we need to reduce the fraction. We notice that both 4 and 8 are divisible by 4, so we can divide the numerator and denoninator by 4.

my multiple choice just wants 4/8 and why is it 4/8
mathstudent55
  • mathstudent55
There is no 1/2 in your choices?
anonymous
  • anonymous
no
mathstudent55
  • mathstudent55
Then 4/8 is correct.
