Answer:
Mariana takes the two pills together after 18 hours.
Step-by-step explanation:
Mariana must take two pills; one every 6 hours and another every 9 hours.
She take two pills together. Let she takes the two pills together after t hours at the time when she take initially.
To find the time to take the two pills together, take the least common multiple of 6 and 9.
6 = 2 x 3
9 = 3 x 3
So, the least common multiple is 2 x 3 x 3 = 18
So, she takes the two pills together after 18 hours.
A. 6/7
B. 4/5
C. 4/7
D. 11/6
The number that lies between the points 1 and 5/6 is 4/5
A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.
Given here: The proper fraction 5/6=0.83
Now 4/5=0.8
6/7=0.85
11/6=1.83
4/7=0.57
Thus 4/5 must lie between 5/6 & 1
Hence, The correct option is B) 1/5 as no other option lies in the required interval.
