Correct Answer: 0.0027
Correct Answer: always less than either of the original fractions
Explanation:
We can easily Answer this by taking some values.
The question states that the two fractions, each have values between 0 and 1.
Let us say one of the fraction is 1/2 and the other fraction is 1/3 .
The product of the two fractions is 1/2 x 1/3 = 1/6 .
is lesser than both 1/2 and 1/3 .
So, the correct answer is that the product is always less than either of the original fractions.
Correct Answer: 0.018
Correct Answer: 0.04
Explanation:
Given = (11.98)^2 + (0.02)^2 + 11.98 * x.
For the given expression to be a perfecr square, we must have
11.98 * x = 2 * 11.98 * 0.02 => x = 0.04
Correct Answer: 18
Explanation:
Let the present age of person be x years.
Then, 3(x + 3) - 3(x - 3 ) = x <=> (3x + 9) - (3x - 9) = x <=> x = 18..
Correct Answer: 11/17, 7/11, 5/9, 8/15
Explanation:
Converting each of the given fractions into decimal form, we get
5/9 = 0.55, 7/11 = 0.63, 8/15 = 0.533, 11/17 = 0.647
Clearly, 0.647>0.63>0.55>0.533
so , 11/17 > 7/11 > 5/9 > 8/15
