Anuta_ua [19.1K]

Answer:

there will 7 pencils, 19 pens and 3 erasers in each bag of gift bag and total number of gifts bag will be 9.

Step-by-step explanation:

Given:

Number of pens = 171 pens

Number of pencils = 63

Number of erasers = 27

We need to number of each items in the bags.

Solution:

First we will find the largest number of gift bags that can be packed.

To find the  the largest number of gift bags that can be packed we need to find the greatest common factor of these numbers.

So we will List  the prime factors for each number:

171 = 3 \times 3 \times 19\\\\63 = 3 \times 3 \times 7\\\\27 = 3 \times 3 \times 3

From above we can say that;

The greatest common factor of three numbers = 3\times3=9

Hence There would 9 gifts bag to packed this item.

Now To find the Number of item in each bag we will divide number of items from the number of gifts bag.

framing in equation form we get;

Number of pencils in each = \frac{63}{9}=7\ pencils

Number of pens in each bag = \frac{171}{9}=19\ pens

Number of eraser in each bag = \frac{27}{9}=3\ erasers

Hence there will 7 pencils, 19 pens and 3 erasers in each bag of gift bag and total number of gifts bag will be 9.

The length and breadth of a rectangular playground are 110m and 90m. Find the ratio of:
boyakko [2]

The length and breadth of a rectangular playground are 110m and 90m.

(a) Ratio of length to perimeter = 11 : 40

(b) Ratio of breath to perimeter = 9 : 40

<u>Solution: </u>

Given that length of play ground = 110 m

And breadth of playground = 90 m

Need to determine ration of (a) length to perimeter and (b) perimeter to breadth

Lets first calculate perimeter of rectangular playground

<em>Perimeter of Rectangle = 2(length + breadth )  </em>

=> Perimeter of Rectangular playground = 2(110 + 90) = 400 square meter

Now substituting values in ratio we get,

(a) Ratio of length to perimeter = 110 : 400 = 11 : 40

(b) Ratio of breath to perimeter = 90 : 400 = 9 : 40
