Question

[Phạm Đức Nhân]

There are 15 apples and oranges in total. The ratio of apples to oranges is 3 : 2. What are the numbers of apples and oranges?

• 9, 6
• 5, 6
• 9, 8
• 8, 6

Answer 1

[The Angry]

Set the number of oranges to a, the number of apples to b .

Know that a = 3/2 b, a + b = 15

=> a = 15: (3 + 2) x 3 = 9

<=> b = 15 - 9 = 6

So the number of apples is 9, the orange number is 6 .

Answer 2

[Đặng Mẫn Chi]

Apples:     +----+----+----+   

Oranges:  +----+----+         

The number of apples is:

15 : (3+2) x 3 = 9 ( apples )

The number of oranges is:

15 - 9 = 6 ( oranges )

Ans: oranges: 6

         apples: 9
