Q5) Name the property under multiplication used in each of the following.

(i) \frac{-4}{5}\times1=1\times\frac{-4}{5}=\ \frac{-4}{5}

(ii) \frac{-13}{17}\times\frac{-2}{7}=\ \frac{-2}{7}\times\ \frac{-13}{17}

(iii) \frac{-19}{29}\ \times\ \frac{29}{-19}=\ 1

Answer:

Solution 5:

(i): Multiplicative Property

(ii): Commutative Property

(iii): Multiplicative Inverse Property

"let's see how we're going to solve the
question
so the question says name the property
under multiplication
using each of the formula so to
understand that let's quickly
write the first part the first part is
is
and c is multiplied
into both sides of the equation then the
product
ac will still be equal to bc
similarly here we can see that one
is multiplied on both sides of the
equation
which gives us a filled up same
great let's see the second part so the
second part
by 17 into negative 2 by 7
is equal to negative 2 by 7
into negative 13 by 17.
now let's see which property is this if
you remember
this is become
mutated t
will be good let's see this property
says
this property says if i multiply
a into b and from multiply b
into a then the product will remain
same just to give you an example if you
multiply two and you get
three or
three into two both of them will equal
the
same that's in the last and final part
and which is this property this is
multiplicative inverse property
right and if we remember what this
property says it says
if a is multiplied by its multiplicative
in modes
then the product shall always be
one now these properties are very
important and you should
remember okay thank you
