Question

2/7x+3/7x=2 7/14y:1 1/2=2 1/3*1/3​

Answer 1

Ответ: 2/7x+3/7x=2 7/14 ⇒5*х/7=10*х/14=35/14⇒10*х=35⇒х=3,5

y:1 1/2=2 1/3*1/3​⇒у/1,5=7/9⇒у=1,5*7/9=105/90=1 15/90=1 3/18=1 1/6.

Answer 2

Ответ:

1. х = 3 1/2

2. у = 1 1/6

Пошаговое объяснение:

1. 2/7x+3/7x= 2 7/14

5/7х = 35/14

х = 35/14 : 5/7

х = 35/14 * 7/5

х = 7/2 = 3 1/2

2. y:1 1/2=2 1/3*1/3​

у:3/2 = 7/3*1/3

у:3/2 = 7/9

у = 7/9 * 3/2

у = 7/6 = 1 1/6

Answer 3

It looks like you've provided a set of equations and expressions. Let's break them down one by one:

1. $\frac{2}{7}x + \frac{3}{7}x = 2$: Combine the like terms on the left side of the equation: $\frac{5}{7}x = 2$

   To solve for $x$, multiply both sides by the reciprocal of $\frac{5}{7}$ (which is $\frac{7}{5}$): $x = 2 \cdot \frac{7}{5} = \frac{14}{5}$

2. $\frac{7}{14}y : 1 \frac{1}{2} = 2 \frac{1}{3}$: This appears to be a ratio. To simplify it, let's convert the mixed numbers to improper fractions: $\frac{7}{14}y : \frac{3}{2} = \frac{7}{3}$

   Now, to find the value of $y$, multiply both sides by the reciprocal of $\frac{7}{3}$ (which is $\frac{3}{7}$): $y = \frac{7}{14} \cdot \frac{3}{7} = \frac{3}{14}$

3. $\frac{1}{3} \cdot \frac{1}{3}$: Simply multiply the fractions: $\frac{1}{3} \cdot \frac{1}{3} = \frac{1}{9}$

So, the solutions are:

1. $x = \frac{14}{5}$
2. $y = \frac{3}{14}$
3. $\frac{1}{3} \cdot \frac{1}{3} = \frac{1}{9}$
