The number you are looking for is 12. Reversing the digits gives you 21 75% of 12 is 9 12 + 9 = 21
3(x+21) = 2(x+23)3x+63=2x+46x=-17
To calculate half (1/2) of any number, divide that number by 2.
let X = number X + 1/2 X = 21 1.5 X = 21 X = 14
It is 16. This is because there are five numbers between 11 and 16, and there are five numbers between 16 and 21 :]

21
The numbers that go into 21 are 1, 3, 7, and 21, while the factors of 16 are 1, 2, 4, 8, and 16. To find common factors of both numbers, we identify the factors of 21 and 16, which only share the number 1. Hence, the greatest common factor (GCF) of 21 and 16 is 1.

33 over 16 as a mixed number = 21/16
Order them: 15 16 17 21 21 Find the middle one: 17 That is the median
Mean is another word for average. To find the mean , add the terms, then divide by the number of terms. Hence [21 + 25 + 36 + 16 + 32] / 5 130/5 = 26 The mean value.
3(x+21) = 2(x+23)3x+63=2x+46x=-17
Expressed as a mixed number in its simplest form, 21/16 is equal to 1 5/16 or one and five sixteenths.
The question does not make sense. 21/16 is one number: there is no second number in which it needs to go.
16 and 21 only have one common factor, the number one.
