Question

(240+390):y=70 3m:6 4СМ:8 27см*6 43мм*6

Answer 1

(240+390)/у=70

630/у=70

У=630/70

у=9

3м/6=0,5м=50 см

4см/8=0,5см=5 мм

27 см*6=162 см=1м 62 см=1,62 м

43 мм*6=258 мм=25см 8 мм=25,8см

Answer 2

It looks like you've provided a mix of mathematical expressions and measurements. Let's break down and solve each part:

1. (240 + 390) / y = 70: To solve for 'y,' you can first simplify the left side of the equation: 630 / y = 70

   Now, to isolate 'y,' you can multiply both sides of the equation by 'y': 630 = 70y

   Finally, divide both sides by 70 to solve for 'y': y = 630 / 70 y = 9

2. 3m : 6: It appears to be a ratio, and you can simplify it by dividing both parts by their greatest common factor, which is 3: (3m) / 3 : 6 / 3 m : 2

3. 4СМ : 8: Similarly, this seems to be a ratio. You can simplify it by dividing both parts by their greatest common factor, which is 4: (4СМ) / 4 : 8 / 4 СМ : 2

4. 27см * 6: To calculate the product, multiply 27 by 6: 27 * 6 = 162см

5. 43мм * 6: To calculate the product, multiply 43 by 6: 43 * 6 = 258мм

So, the solutions are:

1. y = 9
2. m : 2
3. СМ : 2
4. 27см * 6 = 162см
5. 43мм * 6 = 258мм
