Answer:
38/50 ; or 19/25
Step-by-step explanation:
One way could be that you add all the marbles together to get your total marbles; 12 + 10 + 15 + 13 = 50.
Then you add all the colours expect red; 10 + 15 + 13 = 38.
Which would give me 38/50; which simplifed would be 19/25
Answer:
31 is a prime number.
How to tell if a number is prime: estimate the square root. In this case, we know the square root of 31 is between 5 and 6 and it isn’t divisible by either of those. If it is divisible by a number higher than it’s square root, the other factor must be lower. Is it divisible by 4 or 2? no, because it isn’t an even number. It’s not divisible by 3, because there’s a remainder of 1 if you try. You’ve eliminated all numbers less than the square root, so it is prime
