Question

Find the product:-
$( \frac{7}{23} \times \frac{5}{19} ) \times \frac{1}{2}$
Please give me answer ಠ_ಠ​

Answer 1

Answer:

We have studied procedures for working with fractions in earlier grades.

a

b

×

c

d

=

ac

bd

(b≠0;d≠0)

a

b

+

c

b

=

a+c

b

(b≠0)

a

b

÷

c

d

=

a

b

×

d

c

=

ad

bc

(b≠0;c≠0;d≠0)

Note: dividing by a fraction is the same as multiplying by the reciprocal of the fraction.

In some cases of simplifying an algebraic expression, the expression will be a fraction. For example,

x2+3x

x+3

has a quadratic binomial in the numerator and a linear binomial in the denominator. We have to apply the different factorisation methods in order to factorise the numerator and the denominator before we can simplify the expression.

x2+3x

x+3

=

x(x+3)

x+3

=x(x≠−3)

If x=−3 then the denominator, x+3=0 and the fraction is undefined.

Answer 2

Step-by-step explanation:

$( \frac{7}{23} \times \frac{5}{19} ) \times \frac{1}{2} \\ \\ = \frac{7}{23} \times \frac{19}{5} \times \frac{1}{2} \\ \\ = \frac{103}{115} \times \frac{1}{2} \\ \\ = \frac{103}{230}$
