The highest common factor (h.c.f) of 10 and 20 is 10. This is because 10 is the largest number that can evenly divide both 10 and 20.
Round 15 to the nearest 10 would be 20, as it is closer to 20 than 10.
There are 10 neutron in a neon atom. We just leaned this in my class. The atomic number is 10 so there are 10 protons and 10 electrons. You subtract the atomic number from the atomic mass: 20-10=10. There are 10 neutrons.
An atom of neon consists of 10 protons, 10 neutrons and 10 electrons (atomic number = 10; atomic mass = 20)
To make 10 volume developer from 20 volume developer, you can mix equal parts of 20 volume developer and distilled water. For example, mix 1 part of 20 volume developer with 1 part distilled water to create 10 volume developer.

HCF is the highest common factor of two or more numbers. HCF of 20 and 30 is 10.
LCM is 20 and the hcf is 10
10
It is: 10
It is 10
2 and 20 have an HCF of 2 and an LCM of 20. You could also use 4 and 10.
The GCF is 5.
The answer is 4 and 10.
The GCF is 10.
To find the HCF of 20 and 30, break them down into their prime factors: 20 = 2x2x5 30 = 2x3x5 The next step is to identify any common prime factors. In this case both numbers have a 2 and a 5 as prime factors. Multiply these together and you get: 2x5 = 10 Therefore the HCF of 20 and 30 is 10.
The GCF is 2.
5 (leaves you with 2, 4 and 7)
