Objective:
In this lesson we will learn how to use multiplication in our everyday activities.
Example 1
Three students were taught some poems. Each student learnt 25 poems. How many poems were learned in all?
Solution
Number of students = 3
Number of poems learnt in all = 25 x 3
∴ 75 poems were learnt in all
Example 2
There are 6 boxes of apples. Each box contains 56 apples. How many are there in all the boxes?
Number of boxes = 6
Number of apples in each box = 56
Number of apples in all = 56 x 6
∴ There are 336 apples in all.
Example 3
We wanted to buy 7 cakes for John’s birthday. Each cake cost 64 pence. How much will the 7 cakes cost?
Number of cakes = 7
Cost of a cake = 64 pence
Cost of 7 cakes = 64 x 7
∴ 7 cakes will cost 448 pence or £ 4.48
