Answer:

25%

Step-by-step explanation:

$3 pent out of the original $12. We can ask what is the percentage of $12 that is equal to $3? This can be written as:

X($12) = $3, where X is the percentage.

X = (3/12)

X = 0.25 or 25%

In Art class, Mr. Jocelyn gave everyone a1 foot stick to measure and cut. Vivian measured and cut her stick into 5 equal pieces.

matrenka [14]

No. The more you cut, the less the one-piece length is. The pieces that Vivian has is less than Scott.

However, they all got a 1-foot stick. So, if you add them up you have an equal length.

A bowl of fruit contains only strawberries and grapes. For every 2 strawberries in a bowl there are 5 grapes.

sdas [7]

Answer:

See Explanation

Step-by-step explanation:

Given

Let:

$S \to$ Strawberry

$G \to$ Grape

The given parameter can be represented as:

$S : G = 2 : 5$

Required

The question is incomplete as what is required is not stated.

Possible questions could be to determine the number of strawberries given a certain number of grapes, and vice versa

Take for instance

Calculate the number of grapes when there are 20 strawberries

We have:

$S : G = 2 : 5$

This becomes

$20 : G = 2 : 5$

Express as fraction

$\frac{20}{ G} = \frac{2 }{5}$

Make G the subject

$G = 20 * \frac{5}{2}$

$G = 10 * 5$

$G = 50$

<em>i.e. 50 grapes</em>

<em>Apply the same method given a certain number of grapes</em>
