Answer:

A. = [tex]\frac{7}{2}[/tex] , in decimal= 3.5 or 3 [tex]\frac{1}{2}[/tex]

B.= [tex]\frac{7}{30}[/tex]

C. = - 0.7 (NEGATIVE SIGN)

D.=0.7 ( POSITIVE SIGN)

Order Of Operations is:

First,

  1. Multiplication
  2. Division
  3. Addition
  4. Subtraction

Step-by-step explanation:

Simplify

6.6-3.2 + [tex]\frac{1}{10}[/tex] =    

First, Subtract (6.6 - 3.2)

= 3.4

Then with the fraction, add the result of the subtaction by the fraction:

= 3.4 + [tex]\frac{1}{10\\}[/tex] , using happy face method

Multiply denominators (1×10) and multiply in X (3.4×10) + (1×1)

= [tex]\frac{3.4}{1}[/tex] + [tex]\frac{1}{10}[/tex] =[tex]\frac{34+1}{10}[/tex]=[tex]\frac{35}{10} =\frac{7}{2}[/tex]    

Answer : [tex]\frac{7}{2}[/tex] , in decimal= 3.5 or 3 [tex]\frac{1}{2}[/tex]

A. [tex]\frac{1}{7}[/tex] ÷ [tex]10[/tex]

=  [tex]\frac{1}{7}\div \frac{10}{1}[/tex]

= [tex]\frac{1\cdot \:1}{7\cdot \:10}[/tex]

Answer: [tex]\frac{1}{70}[/tex]

B. [tex]\frac{7}{3}\div \:10[/tex]

= [tex]\frac{7}{3}\cdot \frac{1}{10}[/tex]

Answer: [tex]\frac{7}{30}[/tex]

C. - 7/10

= - 0.7 (NEGATIVE SIGN)

D. 7/10

= 0.7 ( POSITIVE SIGN)

Hope it help you :)
