Question

Б) 2/5*х=1 1/5 г) х*6=1/5 е) 3*х=1/3

Answer 1

б) 2/5×Х=1 1/5
2/5×Х=6/5
Х=6/5:2/5
Х=6/5×5/2
Х=6/2
Х=3

г)Х×6=1/5
Х=1/5:6
Х=1/5×1/6
Х=1/30

е) 3×Х=1/3
Х=1/3:3
Х=1/3×1/3
Х=1/9

Answer 2

To solve each equation, follow these steps:

a) 2/5 * x = 1 1/5

To get rid of the fraction on the right side, convert 1 1/5 to an improper fraction: 1 1/5 = (5 * 1 + 1) / 5 = 6/5

Now, the equation becomes: 2/5 * x = 6/5

To isolate x, multiply both sides of the equation by the reciprocal of 2/5, which is 5/2:

x = (6/5) * (5/2) x = 6/2 x = 3

So, the solution for x is 3.

b) х * 6 = 1/5

To isolate x, divide both sides of the equation by 6:

x = (1/5) / 6 x = 1/5 * 1/6 x = 1/30

So, the solution for x is 1/30.

c) 3 * х = 1/3

To isolate x, divide both sides of the equation by 3:

x = (1/3) / 3 x = 1/3 * 1/3 x = 1/9

So, the solution for x is 1/9.
