The product of the given fractions is 21.
The given expression is 9 × [tex]2 \frac{1}{3}[/tex]
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Now, the product of fraction can be solved by multiplying numerators and write the result in numerator and multiplying denominators and write the result in denominators.
That is, 9 × [tex]2 \frac{1}{3}[/tex] = 9 × [tex]\frac{7}{3}[/tex] = 21

For the experiment of rolling an ordinary pair of dice, find the probability that the sum will be less than 3 or greater than 5.
Answers
According to the given statement the probability that the sum will be less than 3 or greater than 5 = 27/36.
What is Probability?Probability is simply the likelihood of something occurring. When we are uncertain about the result of an event, we might discuss the probabilities of several outcomes—how likely they are. Statistics is the study of occurrences guided by probability.
According to the given information:When two dice are rolled, the total number of possible outcomes is 36.
sum possibilities probability(favorable/ total outcomes of the event)
2 (1,1) 1/36
3 (1,2) , (2,1) 2/36
4 (2,2), (3,1) , (1,3) 3/36
5 (4,1), (1,4),(2,3),(3,2) 4/36
6 (1,5),(5,1),(2,4),(4,2),(3,3) 5/36
7 (2,5),(5,2)(1,6),(6,1),(3,4),(4,3) 6/36
8 (2,6),(6,2), (5,3),(3,5),(4,4) 5/36
9 (3,6),(6,3),(5,4),(4,5) 4/36
10 (5,5),(4,6),(6,4) 3/36
11 (6,5),(5,6) 2/36
12 (6,6) 1/36
probability that the sum will be less than 3 or greater than 5 = probability for the sum to be 2 + probability for the sum to be 6 + probability for the sum to be 7 + probability for the sum to be 8 + probability for the sum to be 9 + probability for the sum to be 10 + probability for the sum to be 11 + probability for the sum to be 12.
= (1/36) + (5/36) + (6/36) + (5/36) + (4/36) + (3/36) + (2/36) + (1/36)
= (1 + 5 + 6 + 5 + 4 + 3 + 2 + 1)/36
= 27/36
According to the given statement the probability that the sum will be less than 3 or greater than 5 = 27/36.

2 3/4 - 5 1/8
Answers
simplified : 11/4 - 41/8
create a common denominator : 11/4x8 is 88/32 and 41/8x4 is 328/32
simplified : 88/32 - 328/32
simplified : 11/4 - 41/4 (divide both of the fractions by 8)
11/4 - 41/4 is -30/4
the answer is -30/4 or -7 2/4 or -7 1/2
Step by step
To add or subtract fractions, the denominator (bottom) has to be the same, so you are working with the same fractional part of the whole.

-8.9 = -9.3
B.
-8.9 > -9.3
C.
-8.9 < -9.3
Answers
A number line will be helpful to compare the two of the given terms. The correct option is B, -8.9 > -9.3.
What is a number line?A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.
The two of the given numbers can be compared as shown below.
-8.9 > -9.3
This is because on a number line, numbers on left are of less value than numbers on the right. And since -8.9 is close to 0, then -9.3.
Hence, the correct option is B, -8.9 > -9.3.
