Question

sub 7.5-3.4
solve this ​

Answer 1

answer-

subtraction of 7.5-3.4=4.1

Answer 2

Step-by-step explanation:

[]STEP1:

17 Simplify —5

Equation at the end of step1:

75 17 —— - —— 10 5

STEP2:

15 Simplify —— 2

Equation at the end of step2:

15 17 —— - —— 2 5

STEP3:

Calculating the Least Common Multiple :

 3.1    Find the Least Common Multiple

      The left denominator is :       2 

      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} 21015011 Product of all 

 Prime Factors 2510

      Least Common Multiple:

      10 

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 Deniminator by  L_Deno 

    Denote the Right Multiplier by  R_Deno 

   Left_M = L.C.M / L_Deno = 5

   Right_M = L.C.M / R_Deno = 2

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 equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

L. Mult. • L. Num. 15 • 5 —————————————————— = —————— L.C.M 10 R. Mult. • R. Num. 17 • 2 —————————————————— = —————— L.C.M 10

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

15 • 5 - (17 • 2) 41 ————————————————— = —— 10 10

Final result :

☆41 —— = 4.10000 10☆
