Solution

• Number of flowers in one bunch = 13

Each flower has 5 petals.

Total petals in the bunch = 13 $\times $ 5

Adding the number in the boxes:

So, 13 $\times $ 5 = 65

Thus, there are 65 petals in a bunch.

• Number of books = 8

Each book has 64 pages.

Total pages in 8 books = 8 $\times $ 64

Adding the number in the boxes:

So, 8 $\times $ 64 = 512

There are 512 pages in all the 8 books.

• Number of rows in assembly = 6

Each row has 17 students.

Total students in 6 rows = 6 $\times $ 17

Adding the number in the boxes:

So, 6 $\times $ 17 = 102

There are 102 students in all the 6 rows.

• Number of designs on a piece of cloth = 17

Each design has 3 flowers in it.

Total number of flowers on the cloth = 17 $\times $ 3

Adding the number in the boxes:

So, 17 $\times $ 3 = 51

There are 51 flowers on the cloth.

Each flower has 5 petals.

Total petals in the bunch = 13 $\times $ 5

Adding the number in the boxes:

So, 13 $\times $ 5 = 65

Thus, there are 65 petals in a bunch.

• Number of books = 8

Each book has 64 pages.

Total pages in 8 books = 8 $\times $ 64

Adding the number in the boxes:

So, 8 $\times $ 64 = 512

There are 512 pages in all the 8 books.

• Number of rows in assembly = 6

Each row has 17 students.

Total students in 6 rows = 6 $\times $ 17

Adding the number in the boxes:

So, 6 $\times $ 17 = 102

There are 102 students in all the 6 rows.

• Number of designs on a piece of cloth = 17

Each design has 3 flowers in it.

Total number of flowers on the cloth = 17 $\times $ 3

Adding the number in the boxes:

So, 17 $\times $ 3 = 51

There are 51 flowers on the cloth.
