Question

1 cm is divided into 25 equal parts then each part is equal to​

Answer 1

Answer:

the answer is 4

Explanation:

Let the number of equal parts be x in which 60 cm = 600 mm has been divided then the length of each part will be 600x.

According to the question, when the number of equal parts has been increased by unity, the length of each equal part has been decreased by 1 mm

So,

New number of parts will be x+1

The new equation will be:

(x+1)(600x−1)=600

Solve the equation (x+1)(600x−1)=600 to determine the value of x as:

(x+1)(600x−1)=600600−x+600x−1=600600x−x=1600−x2=xx2+x−600=0x2+25x−24x−600=0x(x+25)−24(x+25)=0(x+25)(x−24)=0x=−25,24

As the number of equal parts cannot be negative hence, x=24.

Hence, the number of equal parts when 60 cm is divided is 4.

Answer 2

Given:

Total quantity = 1cm

Parts in which it is divided = 25

To Find:

The measure of each part

Solution:

The given question needs the mathematical operation of division.

Here, two numbers are divided with each other to determine a new number.

It it written as - (p÷q)

Thus, according to the question -

Measure of each part = Quantity / Total parts

= 1/25

= 0.04

Answer: The measure of each part is 0.04cm
