Final answer:
Jenny can buy 42 daffodils with £6.39, as each costs 15p and after converting her total amount into pence (639p), dividing by the cost per daffodil gives us the largest number she can purchase.
Step-by-step explanation:
The question asks us to calculate the largest number of daffodils that Jenny can buy with £6.39, given that each daffodil costs 15p. This is a straightforward division problem, where we have to divide the total amount of money Jenny has by the cost of one daffodil.
We first need to convert £6.39 into pence because the price of a single daffodil is given in pence. There are 100 pence in a pound, so Jenny has 639 pence to spend. Dividing 639 pence by the cost of 15 pence per daffodil tells us how many daffodils Jenny can buy:
- Convert pounds to pence: 6.39 × 100 = 639 pence.
- Divide the total pence by the cost per daffodil: 639 ÷ 15 = 42.6.
Since Jenny cannot buy a fraction of a daffodil, she can buy 42 daffodils (the whole number part of the quotient). Therefore, 42 is the largest number of daffodils Jenny can purchase with her money.
