5.47 - (-2.8) pls help me

8.27

Step-by-step explanation:

subtracting a negative number creates a positive

two negatives = a positive

Fraction= 827/100

Desmial= 8.27000

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "2.8" was replaced by "(28/10)". 2 more similar replacement(s)

STEP1:

Simplify 14/5

The equation at the end of step1:

547/100-(0-14/5)

STEP2:

Simplify 547/100    

The equation at the end of step2:

547/100-(-14/5

STEP3:

Calculating the Least Common Multiple :

3.1   Find the Least Common Multiple

The left denominator is:      100

The right denominator is :      5

Number of times each prime factor

appears in the factorization of: Prime

Factor  Left

Denominator  Right

Denominator  L.C.M = Max

{Left,Right}

2202

5212

Product of all

Prime Factors  1005100

    Least Common Multiple:

     100

Calculating Multipliers :

3.2   Calculate multipliers for the two fractions

  Denote the Least Common Multiple by  L.C.M

  Denote the Left Multiplier by  Left_M

  Denote the Right Multiplier by  Right_M

  Denote the Left Denominator by  L_Deno

  Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 1

  Right_M = L.C.M / R_Deno = 20

Making Equivalent Fractions :

3.3     Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example : 1/2  and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate an equivalent fraction, multiply the numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      547

  ——————————————————  =   ———

        L.C.M             100

  R. Mult. • R. Num.      -14 • 20

  ——————————————————  =   ————————

        L.C.M               100  

Adding fractions that have a common denominator :

3.4      Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators, but the sum or difference over the common denominator then reduces to the lowest terms if possible:

547 - (-14 • 20)     827

————————————————  =  ———

      100            100

Final result :

 827          

 ——— = 8.27000

 100          

Hope this helps!
