Answer 1

Answer:

A fraction is either a proper fraction or an improper fraction.

• A proper fraction is a number representing a part of a whole. This

whole may be a single object or a group of objects. An improper

fraction is a number in which numerator is greater than denominator.

• A mixed fraction is a combination of a natural number and a proper

fraction.

• Two fractions are multiplied by multiplying their numerators and

denominators separately and writing the product.

Step-by-step explanation:

• The reciprocal of a non-zero fraction is obtained by interchanging

its numerator and denominator. For example, reciprocal of

3 2 is

2 3 .

• While dividing a whole number by a fraction, we multiply the whole

number with the reciprocal of that fraction.

• While dividing a fraction by a natural number, we multiply the fraction

by the reciprocal of the natural number.

• While dividing one fraction by another fraction, we multiply the first

fraction by the reciprocal of the other.

• While multiplying two decimal numbers, first multiply them as whole

numbers. Count the number of digits to the right of the decimal

point in both the decimal numbers. Add the number of digits

counted. Put the decimal point in the product by counting the

number of digits equal to sum obtained from its rightmost place. For

example, 1.2 × 1.24 = 1.488.

• To multiply a decimal number by 10, 100 or 1000, we move the

decimal point in the number to the right by as many places as many

zeros (0) are the right of one. For example, 1.33 × 10 = 13.3.

• To divide a decimal number by a natural number, we first take the

decimal number as natural number and divide by the given natural

number. Then place the decimal point in the quotient as in the decimal

number. For example,

1.2

4

= 0.3

• To divide a decimal number by 10, 100 or 1000, shift the decimal

point in the decimal number to the left by as many places as there

are zeros over 1, to get the quotient. For example,

1.34 = 0.0134

100

• While dividing one decimal number by another, first shift the decimal

points to the right by equal number of places in both, to convert the

divisor to a natural number and then divide. For example

1.44 = 14.4 = 1.2

1.2 12
