Question

ПОМОГИТЕ!!! ЭТО СРОЧНО!!! Какое число нужно вставить вместо многоточия, чтобы равенство стало верным: ***/7 : 2/21 = 9 и 14/*** : 2/5 = 7/6 РS. Надеюсь понятно.

Answer 1

Х/7 : 2/21 = 9
х/7 * 21/2 = 9 
21 и 7 сокращается,остается
3х/2 = 9
3х=18
х=6
Ответ: х=6

Answer 2

Solving the Equations

To solve the given equations, we need to find the missing numbers that will make the equations true.

1. For the first equation, */7 : 2/21 = 9: - To find the missing number, we can use the following equation: x/7 = 2/21 * 9. - Solving for x, we get: x = (2/21) * 9 * 7. - Calculating the value of x, we find: x = 14.

2. For the second equation, 14/* : 2/5 = 7/6**: - To find the missing number, we can use the following equation: 14/x = 2/5 / 7/6. - Solving for x, we get: x = 14 / (2/5 / 7/6). - Calculating the value of x, we find: x = 15.

Therefore, the missing numbers to make the equations true are 14 and 15 respectively.

I hope this helps! If you have any other questions or need further assistance, feel free to ask.
