Which equation shows the same relationship as 72 x 1/8 = 9?
Nadusha1986 [10]

Hey there!

72 * 1/8 = 9

= 72/1 * 1/8

= 72(1) / 1(8)

= 72 / 8

= 72 ÷ 8

= 9


Thus, the answer could either be:

• 72/1 * 1/8

• 72 / 8

OR

• 72(1) / 1(8) (hence how we possibly received answer number 2)


Good luck on your assignment & enjoy your day!
