Question

Six pencils are equal in value to two rulers. one ruler is equal in value to two erasers. Twelve pencils are equal in value to how many erasers.

Answer 1

6 pencils = 2 rulers
1ruler= 2 eraser

12 pencil = 4 rulers
4rulers=8 eraser
so 8 erasers are equal to 12 pencils

Answer 2

Answer with Step-by-step explanation:

Six pencils are equal in value to two rulers.

i.e. Value of 6 pencils=Value of 2 rulers

Value of 6×2 pencils=Value of 2×2 rulers

Value of 12 pencils=Value of 4 rulers ----------(1)

One ruler is equal in value to two erasers.

i.e. Value of 1 ruler=Value of 2 erasers

Value of 1×4 rulers=Value of 2×4 erasers

Value of 4 rulers=Value of 8 erasers ---------(2)

By equation (1) and (2), we get

Value of 12 pencils = Value of 8 erasers

Hence, Twelve pencils are equal in value to eight erasers
