Ratio and Proportion: 240: X:: 80: 0.8 (Enter numeric value only.)

 

0.004 as a fraction is

\(\frac{4}{1000}=\frac{1}{250}\)

In ratio form \(\frac{1}{250}\) = 1:250

Thus 0.004 as a ratio is 1:250.

To change mL to L, use the relation 1000 mL = 1 L and apply dimension analysis as follows:

\(300\ mL\ast\frac{1L}{1000mL}=0.3\ L\)

Thus, 300 mL is equal to 0.3 L.

Use the relation 1 gallon =128 ounce to change 3 gallons to ounces as follows

\(\frac {3\ gallons \ast 128 ounces}{ 1 gallon}=384 ounces\)Thus, 3 gallons is equal to 384 oz.

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.
