How many ounces are in 9 3/4 pints

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

\(450\ mL\ast\frac{1L}{1000mL}=0.45\ L\)

Thus, 450 mL is equal to 0.45 L.

Use substitution method to determine the value of the given expression. Use 3 in place of X in the given expression.

\(4X^2-5\frac{2}{3}X\)

First convert the mixed fraction into improper fraction as

\(5 2/3=\frac{\left(3\ast5\right)+2}{3}=\frac{15+2}{3}=\frac{17}{3}\)Now the expression becomes

\(4X^2-\frac{17}{3}X\)

In place of X insert 2

\(4\left(2\right)^2-\frac{17}{3}\left(2\right)=4\left(4\right)-\frac{34}{3}=16-\frac{34}{3}\)

\(16-\frac{34}{3}=\frac{16}{1}-\frac{34}{3}=\frac{48-34}{3}=14/3\)

When X=2, the equation reduces to 14/3, which becomes 4 2/3 or 4.67.

Multiply numerators and denominators separately

\(\frac{2}{3}\ast\frac{3}{5}\)

3 is common for the two fractions, so it cancels out as follows

\(\frac{2}{3}\ast\frac{3}{5}=\frac{2}{1}\ast\frac{1}{5}=\frac{2}{5}\)

Use the relation 1 gallon= 128 fluid ounces to convert between gallons and ounces. Then,

\(840\ fluid\ ounces\ast\frac{1\ gallon}{128\ fluid\ ounces}=6.5625\ gallons\)

840 fluid ounces is approximately 6.6 gallons
