Question

If one –eighth of a pencil is black, half of the remaining is yellow
and the remaining 3 ½ cm is blue , then the total length of the
pencil is

Answer 1

Answer:

98cm

Step-by-step explanation:

x=length of pencil(in cm)

(1/8)x = black = 2/16

((16/16)x-(2/16)x)/2 = (1x - (2/16)x)/2 = 3.5cm = yellow

(1x - (2/16)x)/2 = blue = 3.5 cm

1x-(2/16)x = 7

(1/14)x = 7

with algebra you can say that total length is 98.
