<span>Before you can add or subtract
fractions with different denominators, you must first find equivalent
fractions with the same denominator, like this:
<span>Find the smallest multiple (LCM) of both numbers.
<span>Rewrite the fractions as equivalent fractions with the LCM as the denominator.</span></span></span>
Hope i helped!
The number between 4 and -7 is -3/2, so no, the answer is (2, -3/2) which is B
There are the combinations that result in a total less than 7 and at least one die showing a 3:
[3, 3] [3,2] [2,1] [1,3] [2,3]
The probability of each of these is 1/6 * 1/6 = 1/36
There is a little ambiguity here about whether or not we should count [3,3] as the problem says "and one die shows a 3." Does this mean that only one die shows a 3 or at least one die shows a 3? Assuming the latter, the total probability is the sum of the individual probabilities:
1/36 + 1/36 + 1/36 + 1/36 + 1/36 = 5/36
Therefore, the required probability is: 5/36
I’d go with D, you do 350 and multiply it by 0.0425 and do the same with 450 and multiply by 0.0425 and you multiply each of those answers and then add them to 800
40 of the toys weren't dolls. The reason why is 5/8 times 64 is equal to 40.
