Find a point E on CD such that the ratio of CE to CD is 1/8

Question

On the line point C is at -9 and point D is at 7

Answer 1

To move from -9 to +7 on a number line is 16 to the right of -9 and 1/8 of that can be calculated give it a try.

You can also draw a number line and mark it off in increments of 16(1/8) or 2 start counting from -9

Anyway 16 x 1/8 = 2

-9 + 2 = -7 is point E

I hope you find this useful.

Answer 2

CD = 16

1/8 of 16 = 2

add 2 to -9 to get E = -7

CE/CD=1/8

CE/16=1/8

CE=2

If C is at -9, go 2 units to the right to get E=-7
