Rewrite this fact family as a division number sentence
2/3 x 6/3 = N

• 6/3 ÷ N = 2/3
• 2/3 ÷ 6/3 = N
• 2/3 ÷ N = 6/3
• N ÷ 2/3 = 6/3

Choose the fact family that works with the following equation.

5.7 - 2.6 = 3.1

• 2.6 + 3.1 = 5.7

• 3.1 - 2.6 = 5.7

• 2.6 + 5.7 = 3.1

• 5.7 + 2.6 = 3.1

15.07 - 12.2=

• 2.87
• 1.87
• 3.87
