Question

4 1/9x=72 3 2/11x=35 ​

Answer 1

Ответ:

3 целых 2/11x=35

35/11x=35

x=35*11/35

x=11

7 целых 2/3x=9/46

23/3x=9/46

x=9/46*3/23

x=27/1058

4 целых 1/9x=72

37/9x=72

x=72*9/37

x=648/37

x= 17 19/37

Answer 2

To solve the equations:

1. 4 1/9x = 72:

First, let's convert the mixed number into an improper fraction: 4 1/9 = (4 * 9 + 1) / 9 = 37/9

Now, we can rewrite the equation as: (37/9)x = 72

To isolate x, we need to multiply both sides of the equation by the reciprocal of 37/9, which is 9/37: (37/9)x * (9/37) = 72 * (9/37)

Simplifying, we have: x = (72 * 9) / 37

x ≈ 17.568

Therefore, the solution to the first equation is x ≈ 17.568.

2. 3 2/11x = 35:

Again, let's convert the mixed number into an improper fraction: 3 2/11 = (3 * 11 + 2) / 11 = 35/11

Now, we can rewrite the equation as: (35/11)x = 35

To isolate x, we need to divide both sides of the equation by 35/11: (35/11)x / (35/11) = 35 / (35/11)

Simplifying, we have: x = 1

Therefore, the solution to the second equation is x = 1.

To summarize:

1. 4 1/9x = 72 has a solution of x ≈ 17.568.
2. 3 2/11x = 35 has a solution of x = 1.
