So we know there are 5 red and 12 silver marbles, together making 16 marbles.
This would mean that there is a 5/17 chance of choosing a red marble.
When you do the math to convert 5/17 into a decimal, it turns into being a .29 chance.
Convert .29 into a decimal, and you know that you have a 29% chance of grabbing a red marble.
Hope this helped!

Answer:
w = 10
Step-by-step explanation:
Solve for w:
w/4 + 8.25 = 10.75
Put each term in w/4 + 8.25 over the common denominator 4: w/4 + 8.25 = w/4 + 33/4:
w/4 + 33/4 = 10.75
w/4 + 33/4 = (w + 33)/4:
(w + 33)/4 = 10.75
Multiply both sides of (w + 33)/4 = 10.75 by 4:
(4 (w + 33))/4 = 4×10.75
(4 (w + 33))/4 = 4/4×(w + 33) = w + 33:
w + 33 = 4×10.75
4×10.75 = 43:
w + 33 = 43
Subtract 33 from both sides:
w + (33 - 33) = 43 - 33
33 - 33 = 0:
w = 43 - 33
43 - 33 = 10:
Answer: w = 10
The factors of 24 are 1,2,3,4,6,8,12, and 24. The factors of 40 are 1,2,4,5,8,10,20, and 40. The factors of 56 are 1,2,4,7,8,14,28, and 56. 24÷8=3. 40÷8=5. 56÷8=7. Therefore, the GCF of 24,40, and 56 is
