Question

5 crackers cost 30p what will 15 cost

Answer 1

To find the cost of 15 crackers, first calculate the cost per cracker (30p divided by 5) which is 6p per cracker. Then, multiply that cost by 15 to get the total cost for 15 crackers, which is 90p.

Step-by-step explanation:

The question involves a basic proportion calculation, which is part of mathematics. You're given that 5 crackers cost 30p, and you are asked to determine the cost of 15 crackers. To solve this, you can set up a proportional relationship where the cost of the crackers is directly proportional to the number of crackers.

Here's a step-by-step calculation:

• First, find the cost of one cracker. If 5 cost 30p, then one cracker costs 30p / 5 = 6p.
• Now, multiply the cost of one cracker by 15 to find out the cost for 15 crackers. So, 6p x 15 = 90p.

Therefore, 15 crackers will cost 90p.

Answer 2

90p. 15 / 5 is 3 so you need to times the 30p by 3. 30 x 3= 90.
