Mike says that 3/3 o his fraction model is shaded blue. ryan says that 6/6 of the same model is shaded blue. are the two fractions equivalent? if so, what is another equivalent fraction?

Yes, these fractions are equivalent. If you were to multiply the numerator and the denominator of 3/3 by 2, you would get 6/6, meaning that they are equivalent. These fractions are also equal to one whole, which is any fraction where both the top and bottom (numerator and denominator) are the same number, so 1/1, 2/2, 3/3, 4/4, 5/5, 6/6, 7/7, 8/8, etc. are all equal.

Yes, 3/3 and 6/6 are equivalent. some other equivalent fractions are:
1/1
2/2
4/4
5/5
7/7
8/8
9/9
10/10
I hope this helped you :)

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
