21 is a rational number because it is an integer, which can be converted into a fraction.
<u>Step-by-step explanation:</u>
When a denominater and numerator are integers and gives a quotient then it is a rational number.
21/1, where 21 is denominator and 1 is numerator the quotient is 21. Therefore 21 is a rational number which can also be considered as a ratio.

Answer:
h = 15.8
Step-by-step explanation:
200 = 42 + 10h
10h = 200 - 42
10h = 158
h = 15.8
10. The numbers on the horizontal line would be:
1, 2, 3, 4, 5, 6
11. Count how many of each number there is.
1- 3
2- 4
3- 2
4- 3
5- 2
6- 2
So numbers 1 and 4 will both have 3 dots above them and numbers 3, 5, 6 will have 2 dots above them.
The probability that both of them have landed 5 is 1/7.
Two fair dice have been tossed,
The total of their top faces is found to be divisible by 5,
Probability is a branch of mathematics that deals with calculating the likelihood of a given event's occurrence, which is expressed as a number between 1 and 0.
The probability that both of them have landed 5 is
E={(x,y)|x+y=5 or x+y=10, 1≤x,y≤6},
F={(5,5)}.
P(F|E)= 1/7.
Hence, The probability that both of them have landed 5 is 1/7.
