Answer 2

Given:

2 by 5 into minus 3 by 7 - 1 by 14 minus 3 by 7 into 3 by 5​

To find:

The value of 2 by 5 into minus 3 by 7 - 1 by 14 minus 3 by 7 into 3 by 5​

Solution:

The required value is -1/2.

We will use the concept of BODMAS to solve 2 by 5 into minus 3 by 7 - 1 by 14 minus 3 by 7 into 3 by 5​.

Using this, we will first divide, then multiply the respective terms, followed by addition and subtraction.

We will convert the given statement into an expression.

2/5×(-3)/7-1/14-3/7×3/5

Using BODMAS,

=2/5×(-3)/7-1/14-9/35

= (-6)/35-1/14-9/35

We will add the terms with the same denominator.

=(-15)/35-1/14

=(-3)/7-1/14

On taking the LCM, we get

= (-6)/14-1/14

=(-6-1)/14

=(-7)/14

= -1/2

Therefore, the required value is -1/2.
