Few examples on fraction
Milk is sold at $16 per gallon.
Find the cost of \(6\frac{2}{5}\) gallons of milk.
Solution
Cost of one gallon of milk = $16
Therefore, the cost of \(6\frac{2}{5}\) gallons i.e. \(\frac{32}{5}\) gallons will be
\[\begin{align}
&= \frac{{32}}{5} \times 16 \\[0.2cm]
&= 102.4 dollars
\end{align}\]
| \(\therefore\) The cost of \(6\frac{2}{5}\) gallons of milk is \$102.4 |
In a class of 48 students, \(\frac{1}{4}\) of them watch cartoons.
How many students do not watch cartoons?
Solution
Total number of students = 48
Number of students who watch cartoons = \(\frac{1}{4} \times 48 = 12\)
Thus, the number of students who don't watch cartoons \( = 48 - 12 = 36\)
| \(\therefore\) The number of students who do not watch cartoons is 36 |
The snowfall during the first three months in winter was 30.5 inches, 45.25 inches, and 25.25 inches.
What was the total amount of snow in these months?
Solution
\[\begin{align}
\text{ Total amount of snow for three months} \\&= 30.5 + 45.25 + 25.25 \\[0.2cm]
&= \frac{{305}}{{10}} + \frac{{452.5}}{{10}} + \frac{{252.5}}{{10}} \\[0.2cm]
& = \frac{{305 + 452.5 + 252.5}}{{10}} \\[0.2cm]
& = \frac{{1010}}{{10}} \\[0.2cm]
& = 101inches \\[0.2cm]
\end{align}\]
| \(\therefore\) The total amount of snow in 3 months was 101 inches |
Laura spends \(1\frac{1}{4}\) hours reading a book every day.
She read the entire book in 6 days.
How many hours did she take to read the entire book?
Solution
Number of hours Laura reads every day = \(1\frac{1}{4}\) hours = \(\frac{5}{4}\) hrs
She finishes reading the book in 6 days.
Number of hours she took to read the entire book \( = 6 \times \frac{5}{4} = \frac{{30}}{4} = 7\frac{2}{4}\) hours
| \(\therefore\) Laura took \(7\frac{2}{4}\) hours to read entire book |
