Question

При каком значении Х верно равенство 7:4х=49/140

Answer 1

49*4х=140*7

196х=980

х=980:196

х=5

Answer 2

7/4x=7/20 $\frac{x}{y}$

x=1/5

Answer 3

To find the value of X in the equation 7/(4X) = 49/140, you can solve it step by step.

Step 1: Multiply both sides of the equation by 4X to isolate the fraction on one side:

7 = (49/140) * 4X

Step 2: Simplify the fraction on the right side:

7 = (7/20) * X

Step 3: Now, isolate X by dividing both sides by (7/20):

X = 7 / (7/20)

Step 4: Invert the divisor and multiply:

X = 7 * (20/7)

Step 5: Cancel out the 7's:

X = 20

So, when X is equal to 20, the equation holds true: 7/(4*20) = 49/140.
