What time is it if half of what has already passed remains until the end of today?

lukranit [14]

Answer:

Step-by-step explanation:

We know that a day contains 24 hours in total.

The time already passed will be represented by $x$ .

The remaining time would be $\frac{x}{2}$ , becasye half of what has already passed remains until the end of the day.

Basically, the sum of these two expression gives 24 hours in total.

$x + \frac{x}{2} =24\\\frac{3x}{2}=24\\ x=16$

Therefore, the actual time is 4 p.m.

Find ten rational numbers between -1 by 5 and 1 by 2

uysha [10]

Answer:

Step-by-step explanation:

First both the rational numbers should have same denominators. So, find least common denominator

Least common denominator is 10

$\frac{-1}{5}=\frac{-1*2}{5*2}=\frac{-2}{10}\\\\\\\frac{1}{2}=\frac{1*5}{2*5}=\frac{5}{10}\\\\\\$

Now multiply the numerator and denominators of the both the numbers by 10.

$\frac{-2*10}{10*10}= \frac{-20}{100} \ and \ \frac{5*10}{10*10}=\frac{50}{100}\\\\\\Now\ 10 \ rational \ numbers \ between\frac{-20}{10} \ and \ \frac{50}{100} \ is \\\\\\\frac{-19}{100},\frac{-18}{100},\frac{-17}{100},\frac{-16}{100}.\frac{-15}{100},\frac{-14}{100},\frac{-13}{100},\frac{-12}{100},\frac{-11}{100};\frac{-10}{100}$
