The HCF of both numbers is 6
Firstly, a factor of a number is another number that you can divide it by and get a whole number. The factors of 40 are: 1,2,4,5,8,10,20 and 40 The factors of 30 are: 1,2,3,5,6,10,15 and 30 Now, to find the GREATEST common factor of 40 and 30 , we would have to find the biggest number that goes into both 40 AND 30. After reading the factors above, we can see that 10 is the highest number that goes into both numbers, therefore 10 is the greatest common factor of 40 and 30.
.28 goes between 30-40mph
First, you find a number that goes into both 12 and 30. This number is two. Two goes into 12, six times and 30, fifteen times. So now you have to find a number that goes into both six and fifteen. This number is 3. Three goes into six two times and fifteen five times. There is no number that can go into 2 & 5 besides one. So two fifths (2/5) is your simplified fraction. or two over five.
Put them in order as 28 30 30 31 31 and the median is the number in the middle, which is 30.
When 40 is decreased by 30% the result is 28.
