Question

Show step by step and solve will mark brainly) 7h/12 – 4h/12=18/12

0

h=6

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides:

7*h/12-4*h/12-(18/12)=0

h      h   3

((7•——)-(4•——))-—  = 0

h           h      3

((7 • ——) –  (4 • ——)) –  —  = 0

h     h     3

((7 • ——) –  —) –  —  = 0

Least Common Multiple:  12

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

L. Mult. • L. Num.      7h

——————————————————  =   ——

L.C.M             12

R. Mult. • R. Num.      h • 4

——————————————————  =   —————

L.C.M              12

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

7h – (h • 4)     3h

————————————  =  ——

12          12

3h    3

—— –  —  = 0

12    2

Find the Least Common Multiple

The left denominator is :       4

The right denominator is :       2

Least Common Multiple:  4

Making Equivalent Fractions :

Rewrite the two fractions into equivalent fractions

L. Mult. • L. Num.      h

——————————————————  =   —

L.C.M             4

R. Mult. • R. Num.      3 • 2

——————————————————  =   —————

L.C.M               4

Adding fractions that have a common denominator :

h – (3 • 2)     h – 6

———————————  =  —————

4            4

h – 6

—————  = 0

4

Now,to get rid of the denominator, multiply both sides of the equation by the denominator.

h-6

——— • 4 = 0 • 4

4

Now, on the left hand side, the  4  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

h-6  = 0

Solve  :    h-6 = 0

h = 6
