If a box contains 6 chocolates, how many chocolates are there in 10 such boxes? Shall we calculate the number of chocolates in boxes?
Number of chocolates,
one box = \( 6 = 6 \times 1 = 6 \)
two boxes = \( 6 + 6 = 6 \times 2 = 12 \)
three boxes = \( 6 + 6 + 6 = 6 \times 3 = 18 \)
four boxes = \( 6 + 6 + 6 + 6 = 6 \times 4 = 24 \)
Ten boxes = \( 6 + 6 + \dots 10 \text{ times} = 6 \times 10 = 60 \)
If 6 fans are needed for one room. How many fans are needed for 9 rooms?
Solution:
To find the total fans we have to multiply 9 by 6.
54 fans are needed for 9 rooms.
\( 9 \times 6 = 54 \)
1. \( 4 \times 6 = \) 24
2. \( 7 \times 6 = \) 42
3. \( 8 \times 6 = \) 48
4. In a shirt there are 6 buttons, how many buttons will there be in 8 shirts?
No. of buttons in 1 shirt = 6
No. of buttons in 8 shirts = \( 8 \times 6 \)
