Fill in the missing number in the equation below. Then, describe how you can use number relationships to fill in the blank without having to find the answer to 16 x 14. (use the show your work section.

______ x 28 = 16 x 14

18 x 120 = 9 x 240

Use the show your work section to describe how you can use number relationships to tell whether the equation is true or false without having to find the answer on both sides.

(3 x 4) x 6 = 3 X (4 x 6)

Use the show your work section to describe how you can use number relationships to tell whether the equation is true or false without having to find the answer on both sides.

58 x 17 = (60 x 17) + (2 x 17)

Use the show your work section to describe how you can use number relationships to tell whether the equation is true or false without having to find the answer on both sides.
