Answer 1

Step-by-step explanation:

-1/2×(-3/4) ( ) -3/4×-1/2

3/8 ( = ) 3/8

both the given fractions are equal

Answer 2

Step-by-step explanation:

$\frac{ - 1}{2} \times ( \frac{ - 3}{4} ) \\ = \frac{3}{8}$

$( \frac{ - 3}{4} )( \frac{1}{2} ) \\ = \frac{ - 3}{8}$

What do we observe ?

We observe that when we multiply –1/2 × – 3/4, we get 3/8 and when we multiply –3/4 and 1/2, we get –3/8.

Note:

Adding and multiplying combinations of positive and negative integers can cause confusion.

So, always keep in mind that :

Two ‘pluses’ make a ‘plus’. Two ‘minus’ make a ‘minus’. And a plus and a minus make a minus.
