2/15+1/15=3/15 which isn't less than a half

2/15+8/30=2/15+4/15=6/15 which isn't less than a half

2/15+5/15=7/15 which isn't less than a half

and 2/15+8/15=10/15 which is greater than a half, and when cancelled down is 2/3 which is definitely greater than a half:)

Determine the measures of the angles of MNO if the measures of the angles are in the ratio 2:4:6
saul85 [17]
2:4:6 =2x :4x :6x
2x -1st angle
4x -2d one
6x - 3d one
2x+4x+6x=180 because MNO is a triangle
12x=180
x=180/12=15

2*15=30° -1st angle
4*15= 60° -2d one
6*15=90° - 3d one

Luis tenía un saco de patatas de 95 kg. Ha vendido 10bolsas de 2,5kg cada una. ¿Cuántos kilos de patatas le quedan?
stepan [7]

Answer:

A Luis le quedan 70 kg de patatas.

Step-by-step explanation:

Para encontrar la respuesta, primero tienes que determinar la cantidad total de patatas que Luis ha vendido multiplicando la cantidad de kilos en cada bolsa por el número de bolsas vendidas:

2,5kg*10=25 kg

Ahora que sabes que Luis ha vendido 25 kg de patatas puedes restar esto de la cantidad de kilos que tenía para saber cuánto le queda:

95-25=70

De acuerdo a esto, la respuesta es que a Luis le quedan 70 kg de patatas.
