Numbers between 5 and 10 are numbers between 5 and 10, and numbers between 8 and 14 are numbers between 8 and 14, so the size relationship is uncertain. The former may be bigger and the latter may be bigger or equal.

The different positive divisors of 12 are positive divisors of 12, and there are six kinds: 1, 2, 3, 4, 6, 12 * *.

The number of different positive divisions of 50 is the number of positive factors of 50, including 1, 2,5,10,25,50 * * 6.

So equal

X, y, z are positive integers, z>x>y.

The remainder when z is divided by x refers to the remainder when z is divided by x.

The remainder when z is divided by y refers to the remainder when z is divided by y.

This is uncertain, for example,

For example, 10 >9>8, when the remainder of 10 divided by 9 is less than that of 10 divided by 8.

10 >8>3, then the remainder of 10 divided by 8 is greater than that of 10 divided by 3.

10 >9>3, then the two are equal.

Buying a stereo receiver requires a down payment of 20% of the total cost, with a monthly payment of $30.

The title didn't say * * * months, so the total price can't be determined, and it can't be compared with 450.

In a two-digit number, the number of digits in the unit is twice that of the ten digits.

Two digits and one digit are twice as many as ten digits, so the ten digit must be less than 5, otherwise the one digit will be greater than or equal to 10.
