Question

Joy has a jar filled with plain and chocolate biscuits. There are 26 biscuits in total.The ratio of plain biscuits to chocolate biscuits is 9:4 . How many biscuits are chocolate?

Answer 1

There are 8 chocolate biscuits in the jar based on the ratio of plain to chocolate biscuits (9:4) out of a total of 26 biscuits.

Step-by-step explanation:

The student's question asks how many chocolate biscuits there are if Joy has a total of 26 biscuits in a jar with a ratio of plain biscuits to chocolate biscuits of 9:4. To solve this, we can first determine the total number of parts in the ratio, which is 9 (plain) + 4 (chocolate) = 13 parts. Each part is then equivalent to 26 biscuits ÷ 13 parts = 2 biscuits per part. Knowing this, we can multiply the number of parts for chocolate biscuits by the number of biscuits per part: 4 parts (for chocolate biscuits) × 2 biscuits per part = 8 chocolate biscuits.

Answer 2

Answer: 8

Step-by-step explanation: The total amount of biscuits is 26. The ratio represents the proportion between plain and chocolate. The total is a mix of both using the proportion. The sum of the ratio is 13 which is half of 26. In order to find the amount of chocolate, you just need to multiply the 4 which represents the chocolate proportion by 2 and you get 8 total.
