Nothing.. Because 21 is a Prime number
There is no number that goes into both. must be a trick questionthis is another person not the same one :)the number that goes into 12 and 21 is 3 which is a 5th grade problemwho ever said theres no number that goes into 12 and 21 is WRONG!
341 ÷ 40 = 8 21/40 = 8.525
The HCF of 38 and 40 is 2
40% of 52.5 40/100=0.4 0.4x52.5=21
To determine how many times 21 goes into 40, you would perform division. 40 divided by 21 equals approximately 1.90476. Since you cannot have a fraction of a division, you would round down to get the whole number of times 21 goes into 40, which is 1 time.
1 is the only number that goes into 29 and 40.
Nothing.. Because 21 is a Prime number
To calculate the number of neutrons in an atom of potassium-40, subtract the atomic number (which is 19 for potassium) from the mass number (which is 40 for potassium-40). So, 40 (mass number) - 19 (atomic number) = 21 neutrons in potassium-40.

21/40 is less than 1 and so it can't be expressed as a mixed number
They are: 3*7 = 21 and 2*2*2*5 = 40
the answer is 21. because you do 40-19
341 ÷ 40 = 8 21/40 = 8.525
It is the number 1
21
21 is composite number because it has more than one number that goes into it
