Cuando multiplicas un número positivo y un número negativo, la respuesta siempre será negativa:
4(3) = 12
4(-3) = -12
<span>Para multiplicar fracciones, simplemente multiplique los numeradores y los denominadores en línea recta:
5/4 * 4/7 = 20/28 = 10/14 = 5/7

Answer:
1/8 + 1/2 = 5/8
Step-by-step explanation:
Total number of beads = 8
Number of green beads = 4
Number of yellow beads = 1
Fraction of green beads :
Number of green / total number of bead = 4 / 8 = 1/2
Fraction of yellow beads :
Number of yellow / total number of bead = 1 / 8
Number of green or yellow bead :
1/8 + 1/2 = (1 + 4) / 8 = 5/8
Answer:
d
Step-by-step explanation:
I don't think it really matters if the denominator is negative in a literal equation. Think about a simpler example with numbers. Does it matter whether a fraction is -1/2 or 1/-2? No, they are both the same. Therefore, I would say that the denominator of a literal equation can be negative.
Good luck with your exams!
we can rewrite it as
we can see that 1/4 is in multiple in both terms
so, we can factor it out
so, we get
