Question

Which equation illustrates the division property of equality?

A. d x 4 = 32
d x 4 / 4 = 32 / 4
d = 8

B. d - 4 = 32
d - 4 + 4 = 32 + 4
d = 36

C. d / 4 = 32
d / 4 x 4 = 32 x 4
d = 128

D. d + 4 = 32
d + 4 - 4 = 32 - 4
d = 28

Answer 1

I think it's C because 128 / 4 = 32

Answer 2

division property of equality

if a = b, then a/c = b/c where c is nonzero

Answer 3

in more common language, you might say "divide both sides by ______" (replace the blank with a number or expression)

Answer 4

128 / 4 x 4 = 128
32 x 4 = 128

Answer 5

if we start with d x 4 = 32

we divide both sides by 4 to isolate d

this is using the division property of equality

Answer 6

They all come out as equal but C is the only one that is dividing. A is multiplication, B. is subtraction and D is adding.

Answer 7

what you are showing (in choice C) is the multiplicative property of equality

Answer 8

Well then I'm totally confused

Answer 9

you don't start with dividing

division is the second step

Answer 10

So the division property of equality starts with the opposite, which would be multiplication.

Answer 11

yeah because the goal is to undo the multiplication

Answer 12

start with this
