1.8, 1.9, 2.0, 2.1
Yes, but only if there are no digits after the decimal point. For example, 18, 19, 20, 21 are consecutive numbers in the decimal system.
There are no whole numbers between 20 and 21. Only fractions or decimals exist between these two numbers. Whole numbers between 20 and 25 are 21, 22, 23, and 24.
The percentage is approximately 116.67%. To calculate this, divide 21 by 18 and multiply by 100.
18
In this case, the one that has the least digits.
Yes, but only if there are no digits after the decimal point. For example, 18, 19, 20, 21 are consecutive numbers in the decimal system.
An infinite number of decimals are between any two numbers that aren't the same.
19.5 is halfway between 18 and 21
Try the different numbers - there are only 11 after all - and multiply their digits. Or analyze the factors of the number 21.
21.10, 21.12, 21.13....... and so on.
There are no whole numbers between 20 and 21. Only fractions or decimals exist between these two numbers. Whole numbers between 20 and 25 are 21, 22, 23, and 24.
The percentage is approximately 116.67%. To calculate this, divide 21 by 18 and multiply by 100.
this is a impossible question unless with decimals 2divied by 21= 2+9=18-21=3add a zero then times 15
The least common multiple of 21 , 18 = 126
There are infinitely many numbers. For example, 21.456542700000000000001 21.456542700000000000000005 21.456542700000000002
It is: (18+21)/2 = 19.5
The GCF of 18 and 21 is 3.The prime factorization of 18 is 2*3*3The prime factorization of 21 is 3*7So the GCF of 18 and 21 is 3.You can also notice that the difference between 21 and 18 is 3. The GCF can be no larger than the difference between the numbers. Since 3 is a factor of both 18 and 21, it is the GCF.The GCF is 3.3
