Ken uses 6 apples and 2 bananas to make a fruit salad. He put twice as many oranges as bananas in the salad. How many pieces of
V125BC [204]

Answer:

<u>24 pieces</u> of fruits are use to make 2 fruit salads.

Step-by-step explanation:

Given:

Ken uses 6 apples and 2 bananas to make a fruit salad. He put twice as many oranges as bananas in the salad.

Now, to find the number of pieces of fruit Ken will use to make 2 fruit salads.

So, pieces of fruits use to make a salad are:

Apples = 6.

Bananas = 2.

Oranges = twice of bananas = 2×2=4.

So, total pieces of fruits to make a salad = 6+2+4=12.

Now, total pieces of fruits to make 2 fruit salads:

(6+2+4)\times 2

=12\times 2

=24.

Therefore, 24 pieces of fruits are use to make 2 fruit salads.

How can numbers be expressed, ordered and compared?
USPshnik [31]
Numbers can be expressed, ordered and compared by a lot of mathematical principles, properties, models and paradigms. There are different properties of numbers to associate, group and distribute numbers. For example commutative property of addition, 1 + 2 = 3 can be 3 = 1 + 2. Moreover, numbers can be expressed by mathematical form, thus 100 wherein 1 is in the place order of hundreds. And so on… other examples can be mathematical symbols or inequality to compare numbers. For example, 1 > 2. One is less than 2.
