What you have to do is you add up all the numbers then you divide by the number of numbers. ex. Say you have the numbers 45,56,39 and 35 you add them all up 45+56+39+35=175 then you divide 175/4(because there is 4 numbers)=43.75

To find this, you need to split the numbers into their prime factors: 45 = 3x3x5 27 = 3x3x3 The next step is to identify any common prime factors. In this case, both numbers have two 3s as prime factors. Multiply these together and you get 9. Thus the HCF of 45 and 27 is 9.

They are: 36+9 = 45

Simply add the numbers up For example, If the area of a semicirce is 20cm squared and the area of a rectange is 25cm squared, then the total area would be 20 + 25 = 45

divide 45 by 5 and multiply by 3 45 divided by 5 is 7 times 3 is 21.
