do the same thing but with the formula of cone volume for question 2
a) You have to find the greatest common factor for the values 45 and 54
To do so you have to determine the factors for each value and determine the highest value both numbers are divisible for.
Factors of 45 are
1, 3, 5, 9, 15, 45
Factors of 54 are
1, 2, 3, 6, 9, 18, 27, 54
The greatest common factor is 9, this means that you can divide both numbers by 9 and the result will be an integer:


b) Given the addition

You have to factorize the adition using the common factor.
That is to "take out" the 9 of the addition, i.e. divide 45 and 54 by 9 and you get the result (5+6) but for this result to be equvalent to the original calculation, you have to multiply it by 9
40×28= the answer is 1,120 eggs that he counted
Carl needs 1/2 pair of jeans per day and 1 shirt per day. If he does no laundry, he will require
(1/2 jeans/day)*(14 days) = 7 jeans
(1 shirt/day)*(14 days) = 14 shirts
Carl needs to pack 7 pairs of jeans and 14 shirts.
