Answer :

10% of 710 = 710 * 0.1 = 71
710 - 71 = 639

Answer:

639 points

Step-by-step explanation:

given,

   710 points

to calculate

    10 % decreases

so,

    10 % of 710 points

  = [tex]\dfrac{10}{100} \times 710[/tex]

  =  0.1 × 710

  = 71 points

After decreasing 10% value

  = 710 points -  71 points

  = 639 points

Hence after decreasing 710 points by 10% we get 639 points
