How many gallons are in 576 fluid ounces?

First step is to find the least common divisor of the denominators 19, 25, 5 and 15, which is 1425

Next, multiply each fraction with 1425 as follows

\(\frac{4}{19}\)* 1425=300

\(\frac{4}{25}\)* 1425=228

\(\frac{3}{5}\)* 1425=855

\(\frac{3}{15}\)* 1425=285

From the calculations above, 855 is the largest number among the four computed numbers. Then, it follows that\(\frac{3}{5}\) is the largest number.

To find who ate a bigger share, convert the numbers into decimals and compare them.

\(5/8 \frac{5}{8}\)= 0.625

75% =\( \frac{75}{100}\)= 0.75

0.75 is greater than 0.625, meaning that John ate more than Sally.

The number of boys in a class is 44% of students in a class

\(\frac{44}{100}\ast25=11\ boys\)

Therefore, there are 11 boys in a class.

To add fractions, find the least common divisor of the denominators of 3 and 9, which is 9.

Then:

\(\frac{2}{3}+\frac{4}{9}=\frac{3\left(2\right)+4\left(1\right)}{9}=\frac{6+4}{9}=\frac{10}{9}=1\frac{1}{9}\)
