Question

4
$\frac{4}{5} x - \frac{5}{4} x + \frac{3}{2}$
​

Answer 1

Step-by-step explanation:

4*x / 5 - 5 * x / 4 + 3/2

4x/5 - 5x/4 + 3/2

Taking Lcm of 5,4 and 2 .

Lcm of 5 , 4 and 2 = 20

Now,

4x /5 - 5x/4 + 3/2

4x × 4 - 5x × 5 + 3 × 10 / 20

16x - 25x + 30/20

-9x + 30/20 [ Answer ]

Hope it will help you :))

Answer 2

Answer:

• According to the question, $\sf \frac{4}{5} x - \frac{5}{4} x + \frac{3}{2}$.

Calculations:

= 4(x)/5 - 5(x)/4 + 3/2

• Note, 4 (x) = (4 × x) or (4x).

= [(4x/5 - 5x/4) + 3/2]

New, taking LCM for (5,4) and (2). we get:

• LCM = (5, 4) and (2) = 20

Step-by-step:

= [(4x/5 - 5x/4) + 3/2]

= [(4x × 4) - (5x × 5) +(3 × 10/20)]

= [(16x - 25x) + (30/20)]

= -9x + 30/20

Therefore, -9x + 30/20 is the answer.
