Explanation:

Answer 2

P.E.M.D.A.S (Parentheses, Exponents, Multiplication, division, Addition, and Subtraction)

Since there is no Parentheses or Exponents or Multiplication we have to Divide

6.4 - 2.4 ÷ 6.4 - 2.4 ÷ 0.1

So divide 2.4 and 16.4

2.4 ÷ 6.4 = 0.375

Now we have:
6.4 - 0.375 - 2.4 ÷ 0.1

Now divide 2.4 and 0.1

2.4 ÷ 0.1 = 24

Now we have 6.4 - 0.375 - 24

Now subtract

6.4 - 0.375 - 24 = -17.975

Hope this helped
