Multiplication of Units of Mass
We can multiply the units of mass kg and g by a number like
ordinary numbers.
1. Multiply 115 kg by 6.
Hence, 115 kg × 6 = 690 kg
2. Multiply 32 kg 126 g by 7.
Multiply the grams by 7.
126 × 7 = 882 g. Write 882 under g column.
Multiply the kilograms
32 × 7 = 224 kg
Write 224 under kg column.
Hence, 32 kg 126 g × 7 = 224 kg 882 g.
When measurements are given as combination of two units, we can also first convert the bigger units to lower units and then multiply.
Alternative method:
First convert 32 kg 162 g into gram and then multiply by 7.
32 kg 126 g = 32000 g + 126 g
= 32126 g
32126 × 7 = 224882 g
Convert 224882 g into kg
224882 g = 224000 + 882 g
= 224 kg + 882 g
= 224 kg 882 g
Hence 32 kg 126 g × 7 = 224 kg 882 g
3. Multiply 19 kg 763 g by 5.
Solution:
First convert 19 kg 763 g into gram and then multiply by 5.
19 kg 763 g = 19000 g + 763 g
= 19763 g
19763 × 5 = 98815 g
Convert 98815 g into kg
98815 g = 98000 + 815 g
= 98 kg + 815 g
= 98 kg 815 g
Hence, 19 kg 763 g × 5 = 98 kg 815 g

We normally use 12hour clock system. The hour hand of the clock goes round the dial twice a day (24 hours). Some departments like railways, Airlines, etc use 24hour clock system because they do

We will learn how to calculate the time duration in minutes and in hours. Time Duration (in minutes) Ron and Clara play badminton every evening. Yesterday, their game started at 5 : 15 p.m.

The clock shows time in 12 hour cycle. The first cycle of the hour hand completes at 12 o’clock midday or noon. The second cycle of the hour hand completes at 12 o’clock midnight. ‘a.m.’ and ‘p.m.’ are used to represent the time of the day. ‘a.m.’ stands for ante meridiem,

The clock has numbers from 1 to 12 marked on its dial. These numbers divide the clock face into 12 equal parts. Between any two numbers there are 5 small divisions. Each small division represents a minute. So, the minute hand takes 5 minutes more from one number to the next

The hands of clock move from left to right. This is called the clock wise motion. When the minute hand is on the right side of the clock, it shows the number of minutes past the hour. When the minute hand is on the left side of the clock, it shows the number of minutes to

What are the different ways of reading time? There are many ways to read time: (a) When hourhand is exactly at any number and minutehand is at 12, we read the time in full hours. If hour hand is at

In 4th Grade Worksheet on Capacity we will solve different types of problems on standard unit of capacity, conversion of units of capacity, comparison of capacity, addition of units of capacity, subtraction of units of capacity, word problems on addition of units of capacity

Practice the questions given in the worksheet on word problem on measuring capacity (i.e. addition and subtraction). Addition and subtraction of word problems in liters and milliliters

We will discuss about addition and subtraction of measuring capacity. The standard unit of measuring capacity is liter and the smaller unit is milliliter. The short way is to write liter as l and milliliter as ml. The liquid medicines are measured in ml.

Practice the worksheet on addition and subtraction of measuring capacity in liter and milliliter. The questions are related to add, subtract and word problems on finding the sum and difference to

In conversion of measuring capacity we will learn how to convert litres into millilitres, millilitres into litres, litres and millilitres into millilitres and millilitres into litres and millilitres.

In measurement of capacity we will learn about the standard unit of capacity and volume. We know that the maximum quantity of a container or vessel can hold is called its capacity.
