Question

Чтобы делилось на 5 (*+430):5 и еше *умножить 19:5 и (290-*):5 это все разные

Answer 1

Нужно, чтобы вместо * стояло число, кратное 5 (5, 10, 15 и т.д.).
1) (5+430):5 = 435:5 = 87.
2) 10*19:5 = 190:5 = 38
3) (290-15):5 = 275:5 = 55

Answer 2

I will try to answer your question in detail. To divide by 5, you need to find a number that, when multiplied by 5, gives the desired result. For example, to find (* + 430): 5, you need to solve the equation 5 * x = * + 430, where x is the unknown number. You can do this by subtracting 430 from both sides and then dividing by 5. The answer is x = (* - 430) / 5. Similarly, to find (290 - *): 5, you need to solve the equation 5 * y = 290 - *, where y is the unknown number. You can do this by adding * to both sides and then dividing by 5. The answer is y = (290 + *) / 5. To multiply by 19: 5, you need to multiply the numerator and the denominator by the same number. For example, to find * * (19: 5), you need to multiply both 19 and 5 by *. The answer is (* * 19): (* * 5). You can also simplify the fraction by dividing both 19 and 5 by their greatest common divisor. For example, if * = 5, then (5 * 19): (5 * 5) = 19: 5.

I hope this helps.
