Answer: The two ratios that are equivalent to 4:18 include 2:9 and 8:36
Step-by-step explanation:
To be able to solve this question, we've to simplify the given ratio. Therefore, 4:18 will be reduced to the lowest term and this will be:
= 4/18 = 2/9
Also, when 4/18 is multiplied by 2 for both the numerator and denominator, the value will be:
= 4×2/18×2
= 8/36
Therefore, the correct options will be B(2:9) and E(8:36).
it is easy.....
first, convert this ratio into a fraction
4 : 18 = 4/18
now , equivalent fractions
= 4 = 4 × 2 , 4 × 3
18 = 18 × 2 ,18 × 3
now answer
= 4/18 , 8/36 , 12/54
again covert into ratio
= 4:18 , 8:36 , 12:54
36 and 2 are (the GCF and the LCM)
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.

Answer:
7/80
Step-by-step explanation:
Given that: P(B) = 7 / 20, P(A|B)= 1 / 4
Bayes theorem is used to mathematically represent the conditional probability of an event A given B. According to Bayes theorem:
Where P(B) is the probability of event B occurring, P(A ∩ B) is the probability of event A and event B occurring and P(A|B) is the probability of event A occurring given event B.
