How do you evaluate the following expression using decimals?: #4.56 - 4/5 + 3.21 + 17/32#

Answer 1

#4.56-4/5+3.21+17/32=7.47125#

The best way is to convert each fraction to decimal form. Two of them are already in decimal form. #4/5=(4xx2)/(5xx2)=8/10=0.8# and #17/32=(17xx3125)/(32xx3125)=50125/100000=0.50125#.
Hence, the expression becomes #4.56-0.8+3.21+0.50125=7.47125#

To evaluate the expression using decimals:

  1. Convert the fraction ( \frac{4}{5} ) to a decimal: ( \frac{4}{5} = 0.8 ).

  2. Convert the fraction ( \frac{17}{32} ) to a decimal: ( \frac{17}{32} = 0.53125 ).

  3. Substitute the decimals into the expression: [ 4.56 - 0.8 + 3.21 + 0.53125 ]

  4. Perform the addition and subtraction: [ 4.56 - 0.8 + 3.21 + 0.53125 = 7.50125 ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
