denpristay [2]

Answer:

x=-10

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>
