The formula x divided by Y is equal to more than 50 4. When y is the minimum, x equals (), X must be a multiple of 5 after adding () at least fast

The formula x divided by Y is equal to more than 50 4. When y is the minimum, x equals (), X must be a multiple of 5 after adding () at least fast

When y is the minimum, that is, y = 5, then x = 50y + 4 = 50 * 5 + 4 = 254
X plus at least "1" must be a multiple of 5

In the following formula, the divisor can be divided by the divisor
A. 12÷0.4B. 1.2÷0.4C. 12÷4

In option a and B, the divisor is 0.4, so they are not in line with the meaning of integral division; in option C, 12 △ 4 = 3, the divisor, divisor and quotient are all integers, and the remainder is zero, so 12 can be divided by 4

The divisors of the following three formulas are the same. Can you fill them in?
（ ）/7=（ ）…… four
（ ）/8=（ ）…… seven
（ ）/9=（ ）…… three

（ 39）/7=（5 ）…… four
（39 ）/8=（ 4）…… seven
（ 39）/9=（4 ）…… three
