Convert 3/5 to a decimal

 

First convert 39% to decimal as

39%=39/100=0.39

Now, 0.59>0.39

Use 1 pint =16 ounces to convert between pints and ounces

\(\frac{3}{8}\ pints\ast\frac{16\ ounces}{1\ pint}=6\ ounces\)

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.

\(\frac{9.2}{0.4}=18\)
