nexus9112 [7]

Answer:

7/2

Step-by-step explanation:

Firstly lets put them all in common denominators (LCM) 3,2,4 and 8 re all divided by 24.

17/8 x 3/3 = 51/24

7/2 x 12/12 = 84/24

9/4 x 6/6=54/24

10/3 x 8/8= 80/24

Now lets see which one is greatest: 7/2 or 84/24

Hope this helps :D

N is the set of odd natural numbers greater than 11 and less than 21. Use set notation to write the elements of N. N
S_A_V [24]

Answer:

N = {13, 15, 17, 19}

Step-by-step explanation:

The natural numbers greater than 11 and less than 21 are:

12, 13, 14, 15, 16, 17, 18, 19 and 20

Odd numbers are numbers that have remainders when divided by 2. Out of the numbers above, the numbers with remainders when divided by 2 are 13, 15, 17 and 19.

Since N is the set of odd natural numbers greater than 11 and less than 21,

N = {13, 15, 17, 19}
