**Q.7. Ravi purchased 5 kg 400 g rice, 2 kg 20 g sugar and 10 kg 850 g flour. Find the total weight of his purchases.**

Ans:-

Weight of rice = 5 kg 400 g

= [(5 + 400 / 1000)] kg

= 5.400 kg

Weight of sugar = 2 kg 20 g

= [(2 + 20 / 1000)] kg

= 2.020 kg

Weight of flour = 10 kg 850 g

= [(10 + 850 / 1000)] kg

= 10.850 kg

Total weight of his purchases is

## What We Learn?

- To understand the parts of one whole (i.e. a unit) we represent a unit by a block. One

block divided into 10 equal parts means each part is1/10(one-tenth) of a unit. It can

be written as 0.1 in decimal notation. The dot represents the decimal point and it

comes between the units place and the tenths place. - Every fraction with denominator 10 can be written in decimal notation and vice-versa.
- One block divided into 100 equal parts means each part is 1/100(one-hundredth) of

a unit. It can be written as 0.01 in decimal notation. - Every fraction with denominator 100 can be written in decimal notation and

vice-versa. - In the place value table, as we go from left to the right, the multiplying factor becomes 1/10 of the previous factor. The place value table can be further extended from hundredths to 1/10 of hundredths i.e. thousandths 1/1000 which is written as 0.001 in decimal notation.

- All decimals can also be represented on a number line.
- Every decimal can be written as a fraction.
- Any two decimal numbers can be compared among themselves. The comparison can

start with the whole part. If the whole parts are equal then the tenth parts can be

compared and so on. - Decimals are used in many ways in our lives. For example, in representing units of

money, length and weight.

### What are decimals used for?

We use decimals every day while dealing with money, weight, length, etc. Decimal numbers are used inÂ situations where more precision is required than the whole numbers can provide.

### What is the difference between fractions and decimals?

The main difference between the fraction and decimals is thatÂ fraction represents a ratio between two, while decimals can also be used for writing infinite values and for more precision.

### What are the four operations of decimals?

You should become efficient in using the four basic operations involving decimalsâ€”addition, subtraction, multiplication, and division.
