Answer:
1/5
Step-by-step explanation:
the prob that you will pick a blue marble would be 12/16, easy.
then the prob of picking a yellow marble after that would be 4/15 since one marble is already missing. multiply the numerator and denominator of each fraction. so 12 x 4 and 16 x 15 to get 48/240. then divide each by 48 to get 1/5.
You first have to see if they have the same common denominators. If they do then the operation as in addition you add the numerator and denominator together and she if it can be reduced into a smaller number
I’m not sure if this is right. but wouldn’t it be 0 if he spent the remaining amount of money on supplies for an art project?
37 is a prime number which means it is only divisible by 1 and 37, therefore the only number that can go into 37 and 100 is 1.
Hope it helps. ☺
