3. Total = 32 teeth
4 are canines
Not canines = 32 - 4 = 28 teeth
= 28/32 * 100 = 87.5
= 87.5% are not canines
4. 5 hours sort 45 boxes
1 hour : 45/5 = 9
4 hours : 9 * 4 = 36 boxes
5. Because simple form:
He liked a bouquet with 7 roses and 5 tulips, but he wants to have 24 flowers in his bouquet.
So set he wants to have 7 roses and tulips
then 7 + 5 = 12
24 / 12 = 2
So 7 * 2 = 14
5 * 2 = 10
therefore simple form result:
14 roses and 10 tulips
4 are canines
Not canines = 32 - 4 = 28 teeth
= 28/32 * 100 = 87.5
= 87.5% are not canines
4. 5 hours sort 45 boxes
1 hour : 45/5 = 9
4 hours : 9 * 4 = 36 boxes

6. 288 books and 3/8 of them were English books
So the number of English books in the shop will be:
N = 288 * 3/8 = 108
7. According to the question, Length : width = 5:6
And it’s width is 66 inches, Length : 66 = 5:6
Length = 5 * 66 / 6 = 55 inches
8. ratio = 3:8
Total flowers = 88
Tulips = 8 ratio
Total = 3 + 8 = 11
=> 8/11 * 88 = 64 tulips
So the number of English books in the shop will be:
N = 288 * 3/8 = 108
7. According to the question, Length : width = 5:6
And it’s width is 66 inches, Length : 66 = 5:6
Length = 5 * 66 / 6 = 55 inches
8. ratio = 3:8
Total flowers = 88
Tulips = 8 ratio
Total = 3 + 8 = 11
=> 8/11 * 88 = 64 tulips
