Answer:

14 dvd cases

5 envelopes

Step-by-step explanation:

We need to find the least common multiple of 5 and 14

Find the prime factors

5 = 5*1

14 = 2*7

Multiple them together

2*5*7 = 70

The least common multiple is 70

70/5 = 14 so we need to buy 14 dvd cases

70/14 = 5 so we need to buy 5 envelopes

A farmer has 96 apples to sell at the farmers market. She wants to bag the apples before going. How many ways can the farmer bag
Tcecarenko [31]

Answer and explanation:

Farmer's number of apples = 96 apples

Given that Farmer needs to bag the apples so that there are at least 4 apples in each bag(not less than 4 apples in each bag) and not more than 10 apples in each bag

And also all apples in each bag are equal

We need to find the numbers between 4 and 10(including 4 and 10) that can divide 96 without a remainder

4 can divide 96= 24

5 cannot divide 96 without remainder

6 can divide 96 =16

7 cannot divide 96 without remainder

8 can divide 96=12

9 cannot divide 96 without remainder

10 cannot divide 96 without remainder

From the above we see that the factors of 96 = 4, 6, 8 between 4 and 10

4 apples = 24 bags

6 apples = 16 bags

8 apples = 12 bags

Therefore, there can be 3 possible ways of having equal number of apples in each bag between 4 and 10 apples
