Answer:
The first option is correct, 12/30 and 25/30
Step-by-step explanation:
To get common denominators, you need to find the GFC (greatest common factor) of 5 and 6, which is 30. Then you would need to make the fractions equal the same as the original fractions, by multiplying.
2/5 = ?/30 <- you can see that 30 is 6 times more than 5. so this means you multiply 2 by 6 to get 12. 12/30
5/6 = ?/30 <- you can see that 30 is 5 times more than 6. so this means you multiply 5 by 5 to get 25. 25/30

Answer:
5:3
Step-by-step explanation:
When the ratio says x:y=5:1, it means that x is 5 times greater than y. So, plug in 5 for x and 1 for y.
4(5)+5(1):3(5)
20+5:15
25:15 , if simplified then the ratio 5:3
Answer: The experimental probability that she will roll an even number= 
Step-by-step explanation:
We know that the probability for any event is given by6;-

In a dice, the total even numbers (2,4,6)= 3
Therefore, the probability that she will roll an even number will be given by:-

Hence, The experimental probability that she will roll an even number= 
40÷30s? I think that is the answer, but I'm not completely sure...
