Question

(3 1/8+1 3/4)х=2 1/6

Answer 1

39/8х=13/6
х=13/6:39/8
х=4/9

Answer 2

To solve for x, we first need to simplify the left side of the equation by adding the two mixed numbers:

3 1/8 + 1 3/4 = (38+1)/8 + (14+3)/4 = 25/8 + 7/4 = (25*2+7)/8 = 57/8

So the equation now becomes:

57/8 * x = 2 1/6

Next, we need to convert the mixed number on the right side to an improper fraction:

2 1/6 = (2*6+1)/6 = 13/6

So the equation becomes:

57/8 * x = 13/6

To solve for x, we can cross-multiply:

57/8 * x = 13/6

57 * 6 = 8 * 13 * x

342 = 104x

x = 3.298

Therefore, the value of x is approximately 3.298.
