Will wanted to track the growth of various fruits in his garden, so he decided to label them. His garden had APPLES labeled 1,2,

NARA [144]

Answer:

8 in 11 or 0.7272

Step-by-step explanation:

Between 6 apples. 2 lemons and 3 melons, Will has a total of 11 fruits in his garden. There are three apples labeled with even numbers (2,4 and 6), one melon (2) and one lemon (2), for a total of five fruits.

The probability that a randomly selected fruit is an APPLE or has an EVEN number is given by the probability that it is an apple, P(A), added to the probability that it is even, P(E), minus the probability that it is an even apple, P(A and E):

$P(A\ or\ E) = P(A) +P(E) - P(A\ and\ E)\\P(A\ or\ E) = \frac{6}{11}+\frac{5}{11}-\frac{3}{11} \\P(A\ or\ E) = 0.7272$

There is a 8 in 11, or a 0.7272 chance that the fruit is an APPLE or has an EVEN number.

Fractions are equivalent to 9/8

astraxan [27]

Answer:

9/8, 18/16, 27/24, 36/32, 45/40, 54/48, 63/56, 72/64, 81/72, 90/80, and so on ...

Explanation:

Two fractions are equivalent when they are both equal when written in lowest terms. The fraction 18/16 is equal to 9/8 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (9/8) by the same integer number, ie, multiply by 2, 3, 4, 5, 6 ...

18/16 is equivalent to 9/8 once 9 x 2 = 18 and 8 x 2 = 16

27/24 is equivalent to 9/8 once 9 x 3 = 27 and 8 x 3 = 24

36/32 is equivalent to 9/8 once 9 x 4 = 36 and 8 x 4 = 32
