Question

When measuring distance 12 beads are approximately equat to 6 erasers. how many erasers are equal to 18 beads? How many beads are equal to 42 erasers?

Answer 1

Answer:

9 and 42

Step-by-step explanation:

12b = 6e ➡ 2b = 1e (b : beads, e : eraser)

we can conclude from the equation we created that the ratio of bead to eraser is 1/2

therefore 18b = 9e

and

42 × 2 =84

84b = 42e
