Correct Answer: 166 2/3 million
Explanation:
5% - 2% = 3%
=> 3% ------ 5 million bags
100% ---- ?
=> 166 2/3 million bags.
Correct Answer: FALSE
Explanation:
Any integer 'i' can be written as i = i/1, which is a rational number. Clearly, 7/2,-5/4, etc... are rational numbers but they are not integers.
Hence, from the above analysis, every integer is a rational number but a rational number need not be an integer.
Therefore the given statement that 'Every rational number is an integer' is FALSE.
Correct Answer: 9
Explanation:
3 divided by 1/3
=>
= 3 x 3/1
= 9
Correct Answer: 200 days
