Vocaloid (vocaloid):

hint: (-3/7)-(2/7) = ?

OpenStudy (anonymous):

1/7

Vocaloid (vocaloid):

nope

Vocaloid (vocaloid):

hint: -3-2 = ?

OpenStudy (anonymous):

-5?

Vocaloid (vocaloid):

yup, so (-3/7)-(2/7) = (-5/7)

Vocaloid (vocaloid):

now all thats left is to subtract -3-1 (the whole number part)

Vocaloid (vocaloid):

so we get -4 and (5/7)

OpenStudy (anonymous):

Ready when you are

Vocaloid (vocaloid):

good, just start with the fraction part

Vocaloid (vocaloid):

(3/4)-(5/8) = ?

OpenStudy (anonymous):

I have to find the LCD which in this case is 8

Vocaloid (vocaloid):

good, keep going

OpenStudy (anonymous):

Now I just subtract 5 and 3 which is 2

Vocaloid (vocaloid):

nope, not quite

Vocaloid (vocaloid):

convert 3/4 to a fraction with a denominator of 8

OpenStudy (anonymous):

3/8

Vocaloid (vocaloid):

almost

Vocaloid (vocaloid):

remember, you need to multiply the numerator by 2 as well

OpenStudy (anonymous):

so 6/16?

Vocaloid (vocaloid):

not the denominator, we already multiplied the denominator by 2 to get from 4 to 8

Vocaloid (vocaloid):

3/4 = 6/8

OpenStudy (anonymous):

Oh

Vocaloid (vocaloid):

so (6/8)-(5/8) = ?

OpenStudy (anonymous):

1/8?

Vocaloid (vocaloid):

good

Vocaloid (vocaloid):

now we subtract 8 - 3 to get 6, giving us 6 and 1/8

OpenStudy (anonymous):

Just a few more, thanks for sticking with me lol

Vocaloid (vocaloid):
