Kyle is stringing a necklace with beads he puts black beads on 5/8 of the string and white beads on 1/4 of the string Kyle think
Alexeev081 [22]

Answer:Kyle’s claim is not reasonable

Step-by-step explanation:

Total length of the string of the necklace that Kyle covered with black beads is 5/8.

Total length of the string of the necklace that Kyle covered with white beads is 1/4.

Total length of the string of the necklace that Kyle covered with black beads and white beads is would be

1/4 + 5/8 = 7/8 = 0.875

Kyle thought that he will cover 6/12 of the string with beads. 6/12 = 0.5

It means that he covered more than 6/12. Kyle's claim was wrong

Una familia ha consumido en un día de verano: dos botellas de litro y medio de agua, 5 botellas de 1/4 de litro de jugo de manza
Natalija [7]

Answer:

La familia bebió:

2 botellas de 1.5 L = 2*1.5L = 3L

5 botellas de 1/4 de litro = 5*(1/4 L) = 5/4 L

4 botellas de 1/4 de litro = 4*(1/4 L) = 1 L

Sumando eso, tenemos:

3 L + (5/4) L + 1L = 4L + 5/4 L = (16/4) L + 5/4 L = (21/4) L.

21/4 Litros tomaron en total.

¿podemos directamente sumar y restar fracciones de distintos denominadores?

No, tenemos que tener el mismo denominador para sumar o restar.
