Trish says that if 5/7 of her pencils are yellow, then 2/7 are not yellow. Is she correct. Explain

She's right.
7/7  5/7 = 2/7 
She's right

yes

She's right because you minus 7/7  5/7 =2/7

she's right because if you subtract 7 5 it's 2

24 is 9

Yes, because if 5 out of 7 pencils are yellow, then 2 out of seven ate not yellow because 5  7 = 2
