- A flower has five petals. A bunch of flowers has 13 flowers. How many petals are there in the bunch?
Ans. Number of petals in a flower = 5
Number of flowers = 13
Total number of petals = 13 x 5
13 x 5 means 13 times 5
10 times 5 is 50
So the answer is more than 50
but the answer is less than 100.
Adding 50+ 15 = 65
So, 13 x 5 = 65
Thus, there are 65 petals in a bunch.
- A book has 64 pages. What will be the total number of pages in 8 such books?
Ans. Number of pages in a book = 64 pages
Number of books = 8 books
Total number of pages in 8 books = 64 x 8
64 x 8 means 64 times 8
60 times 8 is 480
So, the answer is more than 480
And 70 times 8 is 560
So, the answer is less than 560
Adding 480 +32=512
So, 64 x8 = 512
Thus, total number of pages in 8 books are
- Students stand in rows in the assembly. There are six rows of students. Each row has 17 students. How many students are there?
Ans. Number of rows in the assembly = 6
Number of students in each row = 17
Total number of students = 17 x 6
17 x 6 means 17 times 6
10 times 6 means 60
So, the answer is more than 60
And 20 times 6 means 120
So, the answer is less than 120
Adding 60+ 42 = 102
So, 17 × 6 = 102
Thus, there are 102 students.
- A design has 3 flowers in it. A piece of cloth has 17 such designs. How many flowers will be on the cloth?
Ans. Number of flowers in a design = 3
Number of designs in a piece of cloth = 17
Total number of flowers = 17 x 3
17 x 3 means 17 times 3
10 times 3 means 30
So, the answer is more than 30
And 20 times 3 means 60
So, the answer is less than 60
Adding 30+ 21 = 51 So, 17 x 3 = 51
Thus, there are 51 flowers.
