One cup is equal to a fourth of a quarter, and in turn, that'd equal back to one cup.
Answer:
The answer to each question is by 5
Step-by-step explanation: 3 to 8 you add 5. 5 to 10 add 5 to 5 to get 10 its a little confusing but once you get it you understand it so well
Answer:
The best thing to do here is to put each of these into fractions, with the total (31) as the denominator.
14/31= silver
6/31= black
8/31= copper
3/31= various colours.
As you're looking for the keys that are silver or copper, you've got to add the two denominators together, which gives you 14+8= 22.
This cannot be simplified further, therefore, the probability of choosing either a silver or copper key is 22/31.
Hope this answer helps you :)
Have a great day
