Answer 2

Answer:

Simplify the given question using addition and subtraction.

Final Answer: 1) 47.50 – 22.36 + 54.5 = 79.64

                       2) 56.4 - 8.333 - 9.707 = 38.360

                       3) 568.75 + 309 - 249.50 - 12.56 = 616.69

                       4) 112.6 - 26.48 - 0.78 + 12.047 = 97.387

Step-by-step explanation:

1)  47.50 – 22.36 + 54.5:

      $47.50- 22.36 + 54.5 = 25.14+54.5$

                   $25.14+54.5=79.64$      

    Answer: 47.50 – 22.36 + 54.5: 79.64  

2) 56.4 - 8.333 - 9.707:

      $56.4 - 8.333 - 9.707=48.067-9.707$

               $48.067-9.707=38.360$

      Answer: 56.4 - 8.333 - 9.707: 38.360

3) 568.75 + 309 - 249.50 - 12.56:

• Here we should add same sign terms. That is, add 568.75 and 309, add 249.50 and 12.56

       $568.75 + 309 - 249.50 - 12.56=877.75-261.06$

                             $877.75-261.06=616.69$

      Answer: 568.75 + 309 - 249.50 - 12.56: 616.69

4) 112.6 - 26.48 - 0.78 + 12.047:

• Here we should add same sign terms. That is, add 112.6 and 12.047, add  26.48 and 0.78

      $112.6 - 26.48 - 0.78 + 12.047= 124.647-27.26$

                             $124.647-27.26=97.387$

      Answer: 112.6 - 26.48 - 0.78 + 12.047: 97.387
