- Question
Which of the following are in descending order of their value?
Options- A. 5/9, 7/11, 8/15, 11/17
- B. 5/9, 8/15, 11/17, 7/11
- C. 11/17 , 7/11, 8/15, 5/9
- D. 11/17, 7/11, 5/9, 8/15
- Correct Answer
- 11/17, 7/11, 5/9, 8/15
ExplanationConverting 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

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: 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: 0.018
Explanation:
In these type of fractions, the decimal moves left the number of zeroes in the divisor times. Herein the given question 18/1000, there are 3 zeros in 1000 (divisor). Hence, the quotient is 0.018.
The quotient of 18/1000 = 0.018.
Correct Answer: 2011
Explanation:
Suppose commodity X wil cost 40 paise more than Y after Z years. Then,
(4.20 + 0.40Z) - (6.30 + 0.15Z) = 0.40
=> 0.25Z = 0.40 + 2.10 => Z= 2.50/0.25 = 10
Therefore, X will cost 40 paise more than Y 10 years after 2001 . i.e in 2011
Correct Answer: 0.001
Explanation:
2 * 5 = 10. Sum of decimal places = 4.
.002 * .5 = 0.0010 = 0.001

Now ,
Correct Answer: 5/3
Explanation:
Given expression =
Correct Answer: 0.125
Explanation:
1/8 to convert into decimal,
Find an equivalent fraction with a denominator of a power of 10.
In this case, we will use 1000.
This can now be written as a decimal with 3 decimal places (because we have thousandths.
i.e, 0.125
Hence,
Correct Answer: 0.625
Explanation:
5/8 is Nothing but to divide 5 into 8 parts.
As 5 is smaller than 8, the quotient starts with a decimal point to make 5 as 50 to be divisible by 8. (0.)
Now 50 goes for 6 times in 8 leaving a remainder 2. (0.6)
Again 2 is smaller than 8, As it already has decimal point in the quotient, now 2 becomes 20.
Now 20 goes for 2 times in 8 leaving a remainder 4. (0.62)
Again 4 is smaller than 8, As it already has decimal point in the quotient, now 4 becomes 40.
Now 40 goes for 5 times in 8 leaving a remainder 0. (0.625)
Therefore, the decimal value of is 0.625.
Now find a decimal value of and Discuss your at Discuss.
Correct Answer: 1/8
Explanation:
125 over 1000 in Simplest Form means in its simple fraction form.
Now, to get the simplest form of 125/1000, find the HCF or GCD of both numerator and denominator i.e, 125 and 1000.
HCF of 125, 1000 = 125
Then, divide both numerator and denominator by 125
i.e,
Hence, is the simplest form of 125 over 1000.
