Step-by-step explanation:
-1/2×(-3/4) ( ) -3/4×-1/2
3/8 ( = ) 3/8
both the given fractions are equal
Step-by-step explanation:
[tex] \frac{ - 1}{2} \times ( \frac{ - 3}{4} ) \\ = \frac{3}{8} [/tex]
[tex]( \frac{ - 3}{4} )( \frac{1}{2} ) \\ = \frac{ - 3}{8} [/tex]
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.
