**Introduction: **

**What is Percent?**

Percent can be defined as “**of one hundred.**”

“**Cent**” comes from Latin and means **100**.

Many words have come from the root cent such as **century, centimeter, centipede & cent.**

Three ways to represent the percent are:

**Grid**

**Number line**

**Equivalent fraction**

**Let’s understand the metric units of mass, what they are in actuality. **

In a class survey, it is found that 6 out of 10 students like maths. Now let’s understand it as percent.

**Now let’s use a different method to understand the percent.**

**Use the number line to represent the percent**

Percent is always compared to 100.

Note: Percent is always compared to **100(As a whole quantity)**

**More Word Problems: Understand Percent**

**Questions1:-** If AB represents 20%, what is the length of line segment that is 100%?

**Solution: **

Here AB = 20%

For 100% = 20% × 5

= 100%

Similarly length of segment is,

= 6 × 5

= 30 m

**Question2: –** If the blue part of the circle represents 20% of students, what is the total strength of students?

**Solution: **

Here, blue part of circle = 20%

For 100% = 20% × 5

= 100%

Similarly total number of students is,

= 30 × 5

** = 150 students.**

**Question3: –** If one part of the rectangle represents 10% of boys in the auditorium, what is the total number of boys in the auditorium?

**Solution: **

Here, one part of rectangle represents = 10%

For 100% = 10% × 10

= 100%

Similarly total number of boys in auditorium,

= 23 × 10

**= 230 boys.**

**Step:** Count the number of different color blocks and divide by total number of blocks.

**Green blocks percent:**

40100=40%40100=40%

**Yellow blocks percent:**

24100= 24%24100= 24%

**Purple blocks percent:**

36100=36%36100=36%
