trisha says that if 5/7 of her pencils are yellow,then 2/7 are not yellow. is she correct? explain
Yes.
7/7 - 5/7 = 2/7
Yes
7/7-5/7=2/7
Yes. 7/7-5/7=2/7
Yes because 5/7 + 2/7 = 7/7
To determine if Trisha's statement is correct, we can use basic arithmetic to find out if the given fractions add up correctly.
Trisha states that 5/7 of her pencils are yellow. This means that out of every 7 pencils, 5 of them are yellow.
Now, if 5/7 of the pencils are yellow, the remaining fraction, 2/7, refers to the pencils that are not yellow.
To confirm if Trisha's statement is correct, we add the fractions:
5/7 (yellow pencils) + 2/7 (non-yellow pencils) = 7/7 (total pencils)
Since the sum of 5/7 and 2/7 equals 7/7, we can conclude that Trisha is correct. All of the fractions add up to the whole, representing all her pencils.
