How many fourths in 4 1/4

Answers

14 fourths, because since 4 fourths make up 1, we would multiply 4 times 4, which gives us 16, and then add the extra 1/4. =)

To determine the number of fourths there are in 4 1/4. Remember that 1+1+1+1 equals 4. Each of the 1's can be written as 1/4+1/4+1/4+1/4. And because 1 = 4 1/4's. Then 4 1's = 16 1/4's. But remember these 16 1/4's are only for the number 4. You must also add the one more 1/4. Altogether there are 17 1/4's present. An easier way to think of this is to convert 4 1/4's into an improper fraction. To determine the number of fourths or 1/4's are present in 4 1/4.

There is an 80% chance of rain tomorrow and a 20% chance the football game will be postponed. What is the probability that it will rain tomorrow and the football game will be postponed?4%

16%

20%

60%

I tried 20 and it's not the answer

Answers

The probability that it will rain tomorrow and the football game will be postponed is 16% option (B) 16% is correct.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

It is given that;

There is an 80% chance of rain tomorrow and a 20% chance the football game will be postponed.

P(rain) = 80%

In decimal

P(rain) = 0.80

P(football game will be postponed) = 20%

In decimal:

P(football game will be postponed) = 0.20

The probability that it will rain tomorrow and the football game will be postponed:

P= P(rain)xP(football game will be postponed)

P = 0.80x0.20

P = 0.16
