Question

Find the missing numbers using suitable properties. Express the answers as rational numbers in their standard forms.

Answer 1

Answer:

if the question is Using the appropriate properties of operations of rational numbers, evaluate the following:

2/5×−3/7−1/14−3/7×3/5.then

the answer is:-

2/5×−3/7−1/14−3/7×3/5

=2/5×−3/7−3/7×3/5−1/14

Taking common term, we get

=−3/7(2/5+3/5)−1/14

=−3/7×(2+3)/5−1/14

=−3/7−1/14

Taking L.C.M. we get,

=(−6−1)/14

=−7/14

=(−7÷7)/(14÷7)

We get,

=−1/2.

Answer 2

Step-by-step explanation:

if the question is Using the appropriate properties of operations of rational numbers, evaluate the following:

2/5×−3/7−1/14−3/7×3/5.then

the answer is:-

2/5×−3/7−1/14−3/7×3/5

=2/5×−3/7−3/7×3/5−1/14

Taking common term, we get

=−3/7(2/5+3/5)−1/14

=−3/7×(2+3)/5−1/14

=−3/7−1/14

Taking L.C.M. we get,

=(−6−1)/14

=−7/14

=(−7÷7)/(14÷7)

We get,

=−1/2.
