Ravi has $20.A pineapple costs $1.45 .Work out the largest number of pineapples Ravi can buy and the change he receives

Step 1: Determine how many pineapples Ravi can buy with his $20. To do this, divide the total amount of money Ravi has ($20) by the cost of one pineapple ($1.45).

$20 ÷$1.45 = approximately 13.79

Since Ravi can't buy a fraction of a pineapple, we round this down to the nearest whole number. So, Ravi can buy 13 pineapples.

Step 2: Calculate the change Ravi receives. To do this, subtract the total cost of the pineapples from the total amount of money Ravi has.

The total cost of the pineapples is 13 (the number of pineapples) times $1.45 (the cost of one pineapple), which equals$18.85.

$20 (Ravi's total money) -$18.85 (the cost of the pineapples) = $1.15

So, Ravi can buy 13 pineapples and will receive $1.15 in change.
