Answer:
2:1
Step-by-step explanation:
2/3 of the class is girls, so that means 1/3 of the class is boys. Make the number of people in the class x. The equasion would be (2/3x)/(1/3x) This simplifies to 2:1
-65, -47, 28, -(-73), 95
To find this, keep in mind the 'larger' the negative number is, the lesser value it holds. Also keep in mind that a negative multiplied with a negative creates a positive.
Hope this helps!
