It is: (12+42)/2 = 27
Thirty 42 - 18 = 24 24 / 2 = 12 18 + 12 = 30 42 - 12 = 30
Thirty 42 - 18 = 24 24 / 2 = 12 18 + 12 = 30 42 - 12 = 30
The difference between 30 and 42 is calculated by subtracting the smaller number from the larger one. So, 42 minus 30 equals 12. Therefore, the difference of 30 and 42 is 12.
32 = 9 42 = 16 12 lies between 9 and 16, so √12 lies between 3 and 4.
The number that goes into both 42 and 12 is their greatest common divisor (GCD). The GCD of 42 and 12 is 6, as 6 is the largest number that can divide both without leaving a remainder. Therefore, 6 is the number that goes into both 42 and 12.
Many ways, but the simplest is add the two numbers together and divide the answer by 2. For example, number between 23 and 42. Add them together: 23 + 42 = 65 Divide by 2: 65/2 = 32.5 So 32.5 is [exactly halfway] between 23 and 42.
42 is exactly halfway between 32 and 52.42
3.5
78
It is: 84
Half way between 36 and 42 is (36 + 42) ÷ 2 = 39.
A number that has exactly an odd number of factors is a power of another number. A number between 10 and 30 that is a power is 16. It is 24 (as well as 42) and its factors are 1, 2, 4, 8, and 16.
