Answer:

Fraction= 827/100

Desmial= 8.27000

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}

2 2 0 2

5 2 1 2

Product of all

Prime Factors 100 5 100

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!
