Answer is:
Obtuse and isosceles
Answer:
Step-by-step explanation:
5 1/3 round to 5 because 1/3 = 0.333 less than 0.5
3 7/9 round to 4 because 7/9 is over 0.5
5+4=9
So, the ration is 17:3, you know that. Therefore, the change from # of students to the 17 is the same change as # teachers to 3. Knowing this, you also know that the total # of people ihas the same change as the total ratio. So 17+3 = 20. 740/20 = 37. So the change is 37. 3x37= 111 17x37=629
You can check to make sure this answer is correct by adding the two final numbers. 111+629 = 740. (Some find it easier to see lined up really pretty)
17 -- 3 total 20
x -- y total 740
Or, if you are visual, look at the picture I drew:
Number 1 : A
Number 2: D
Number 3:B
Number 4:C
Number 5:C
