Question

Use common denominators to determine whether the ratios form a proportion.
6 : 9 and 9 : 12
A.Yes. They form a proportion.
B.No. They do not form a proportion.
please help

Answer 1

Every proportion has a reduced form.

Answer 2

\(6=2\times 3\). \(9=3\times 3\). \[
2\times \cancel{3} : 3\times \cancel 3
\]So \[
6:9 = 2:3
\]

Answer 3

\(12 = 3\times 2\times 2\)\[
\cancel 3\times 3 :\cancel 3\times 2\times 2
\]So \[
9:12 = 3:4
\]

Answer 4

so b?

B is correct.

Answer 6

Answer 12

nope and ya. to 1/6

Answer 13

@wio

Answer 14

wio?

Answer 15

sorry, but \(6/24 \neq 1/6\).

Answer 16

So \[
6 = 2\times 3
\]And \[
24 = 2\times 2\times 2\times 3
\]

Answer 17

If you cancel, you get \[
\cancel{2\times 3}\to 1 \\
2\times 2\times \cancel{2\times 3} \to 2\times 2 =4
\]
