Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below. Good luck!

<u>Step 1:</u><em> Simplify 21.39 + 9 to 30.39.</em>

Basically, add 21 + 9 which equals 30, then add .39 to the end. You will then get 30.39.

What is the value of the expression below -0.75-(-2/5) + 0.4 + (-3/4) help please!!
Reika [66]
-0.75-(-2/5) + 0.4 + (-3/4)

Simplify it :-)

-0.75 + \frac{2}{5} + 0.4 - \frac{3}{4} 

Add the like terms / add your decimals with your decimals & your fractions with your fractions.

(-0.75 + 0.4) + ( \frac{2}{5} - \frac{3}{4} )

Simplify :-)


0.35 + ( \frac{8}{20} - \frac{15}{20} )

Simplify :-)

0.35 + (-\frac{7}{20} )

Now you turn your decimal into a fraction.

0.35 = 35/100 = 7/50

NEW PROBLEM : \frac{7}{50} + + \frac{7}{20} = ??

Make both denominators 100.

\frac{7}{50} × \frac{2}{2} = 14 / 100

7/20 × 5/5 = 35/100

NEW PROBLEM : \frac{14}{100} + \frac{35}{100} = \frac{49}{100}

:-)
