Someone please help :/

Okay what about the other one can ya kind help and guide me through..

4 and 3/4 rounds up to 5
7 and 2/17 rounds down to 7
5*7 = ?

5 *7 = 35

good, so the answer should be around 35

sure.

Oh My! thanks so much!

first find the least common multiple of 6 and 9

18

good, now we convert both fractions to a denominator of 18

right.

|dw:1443667980784:dw|

|dw:1443668011356:dw|

then convert 23/18 into a mixed number

Okay.. so it would be... 1 5/18

good!

ahh so whatever you do to he top do to the bottom?

yup!

Oh ok.

for the second one, convert both numbers to improper fractions

|dw:1443668335836:dw|

|dw:1443668362127:dw|

right. and the second number would be 185/12

|dw:1443668542925:dw|

Ok Just a sec going to do on paper :)

Okay so the -87 one is 261/24?

don't forget the negative sign
-261/24

oops yeah

keep going

the second one is 370/24

good, now add the two fractions together
-261 + 370 = ?

-631

check your math carefully

hint: -261 + 370 = 370 - 261

oh sorry 731

still not right
370 - 261 = ?

109

sorry was adding :s

okay nice!

But I don't have any answer choices that say 4 13/24. do i simplify

huh, what are the answer choices then? is 109/24 a choice?

I hope I didn't make a mistake somewhere ;-:

nope.

see...

oh right I see what I did wrong|dw:1443669786964:dw|

we end up with 4 and 7/24

Ahh Okay I thought I had misunderstood something lol

ready to keep going?

Okay I sorry there is only 8 questions so we are at 5. Thanks again for helping and sticking around

convert 5/8 and 3/10 to the same denominator, any ideas on where to start?

I wasn't typing i think its stuck lol

uh 80.

almost, we can do 40 instead

Yeah I just realized tht thx

okay.. |dw:1443670407961:dw|

good, so 25/40 minus 12/40 = ?

13/40

great! ready for the next one?

yup.

right so 12/16

great, lets keep going

so I subtract 12/16 and 15/16?

yeah, subtract

15-12= ?

is 3/16

good

their LCD is 12.

right?

right, but convert to mixed numbers first

|dw:1443671359350:dw|

aren't I suppose to multiply 10 and 12 then add 11?

|dw:1443671417880:dw|

I am so sorry I had to refresh nd it was loading for ever.

no worries ^_^

so the first one would be -131/12 and the second one would be 29/12

|dw:1443671791958:dw|

not quite

-29/4

now we have
-131/12 and -29/4
change the denominator to 12 now
