(use division to compare.) compare the numbers in the following sequence and try to determine what the next number should be. 6, 9, 18, 21, 42, 45, ?

Question 1)
a) Since 15 is greater than 8, the correct expression will be:
15 > 8

b) Since 4 is less than 134, the correct expression will be:
4 < 134

c) Since 3 is less than 5, the correct expression will be:
3 < 5

d) Since 351 is greater than 215, the correct expression will be:
351 > 215

Question 2:
a) Since 54 and 53 are not equal, the correct expression will be:
54 ≠ 53 

b) Since 8 is equal to 4 + 4, the correct expression will be:
8 = 4 + 4

c) Since 23 + 6 is equal to 6 + 23, the correct expression will be:
23 + 6 = 6 + 23

d) Since 64 is not equal to 99, the correct expression will be:
64 ≠  99

Question 3)
a) Since the two fractions have same denominators, the fraction with larger denominator will be larger. So the correct expression will be:
4/9 < 5/9

b) 8/10 can be simplified to 4/5 by cancelling 2 from numerator and denominator. So the correct expression will be:
4/5 = 8/10

c) If the numerators of two fractions are same, the fraction will smaller denominator will have larger value. So the correct expression will be:
7/12 > 7/15

d) If both numerator and denominator of a fraction are different, we compare them by changing them to fractions with same denominator.
The LCM of 4 an 7 is 28.
3/4 can be written as 21/28. We have multiplied both numerator and denominator by 7.
6/7 can be written as 24/28. We have multiplied both numerator and denominator by 4.
Now both fractions have same denominators and we can compares them easily. So we can write:
3/4 < 6/7

Question 4)
a) Since 0.531 is greater than 0.456, the correct expression will be:
0.531 > 0.456

b) Since 0.63 is greater than 0.47, the correct expression will be:
0.63 > 0.47

c) Since 0.267 is lesser than 0.539, the correct expression will be:
0.267 < 0.539

d) Since 0.07 is lesser than 0.7, the correct expression will be:
0.07 < 0.7

Question 5)
a) To find how much larger is one number than the other, we simply find their difference. For 154 and 27:
154 - 27 = 127
So, 154 is 127 larger than 27

b) 25 - 12 = 13
So, 25 is 13 larger than 12

c) 135 - 127 = 8
So, 135 is 8 larger than 127

d) 46 - 24 = 22
So, 46 is 22 larger than 24

Question 6) 
Cost of TV at store A = $498
Cost of TV at store B = $ 425
The amount Phyllis save will be = $498 - $425 = $73
Thus, Phyllis saves $73 if she buys the TV from store B

Question 7)
Distance traveled by Dan = 5 miles
Distance traveled by Chan= 2.5 miles
Since 5/2.5 = 2
Dan traveled twice the distance as compared to that of Chan's

Question 8)
The given sequence is:
6,9,18,21,42,45,..
If you observe the sequence you will find that first 3 is being added to the number to get the next number
6 + 3 = 9
The result is then doubled to get the next number:
9 x 2 = 18
And this continues..
18 + 3 = 21
21 x 2 = 42
42 + 3 = 45
So the next number in the series will be:
45 x 2 = 90 

Hi i just wanted you and me and you are a nice right off my mind and
