Answers
1. B: The given model represents the fraction, 2/9, which is approximately 0.22. The model for Choice B represents the fraction, 1/8, which equals 0.125. This fraction is less than the given fraction. The fractions can also be compared by finding a least common denominator.
2. B: If they lay the sticks end to end then you would just add the lengths together. First convert 7/8 to14/16 then add that to 5/16 to get 1 3/16.
3. D: The model shows 35 counters, divided into 7 groups, with 5 counters in each group. Therefore, the model represents the number sentence, 35÷7=5.
4. B: The missing number sentence in the fact family is the other division number sentence, which reads:42÷6=7.
5. 477: If he travels 572 miles and then 437 miles then he only has 477 miles left to go. 1486-572-437=477.
