Question

Can someone please please pleeeaaaese help me

Answer 1

The order of operations is:  P-E-M-D-A-S

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

1).  Parentheses:  (1/8 ÷ 1/5)  =  (1/8 · 5/1)  =  5/8
       Multiplication:      5/8 · 7

2).  Parentheses:  (4/6 · 2)  =  4/3
      Exponents:   2³=8,   6²=36
      What does it say now ?  8 ÷ 36 + 4/3 + 6
      Division:                          8 ÷ 36 = 4/18 = 2/9
      What does it say now ?    2/9 + 4/3 + 6

3).  Exponents:  9³ = 729,  3² = 9
      What does it say now ?  729 · 5/8 ÷ 11 · 9
      Rearrange it:                (729 · 5/8 · 9) ÷ (11)

4).  Parentheses:  3-6/8 + 4 = 30/8 + 32/8 = 62/8
     the other one:   3/4 (· 8) = 6    
      What does it say now ?     62/8 x 6 ÷ 3

5).  Exponents:  4³=64,  8²=64
      Parentheses:  (64 + 7-2/7) = 448/7 + 51/7 = 499/7
      the other one:  (64 + 3-4/9) = 576/9 x 31/9 = 1984/9           
      What does it say now ?   499/7 ÷ 1984/9 - 10
      Division:                 499/7 ÷ 1984/9 = 499/7 · 9/1984 = 0.32337... (rounded)
      What does it say now ?       0.32337...  -  10   

6).  Exponents:  6³ = 216
      Parentheses:  9-3/4 - 6³ = 9-3/4 - 216 = 9.75 - 216 = -206.25
      What does it say now ?   -206.25 + 3-5/6  Can you finish it off ?
