6 x 3 = 18 and 3 x 3 = 9. Since 18 > 9, 6 x 3 is more than 3 x 3.


2 x 3 = 6 and 7 x 3 = 21. Since 6 < 21, 2 x 3 is less than 7 x 3.


5 x 4 = 20 and 8 x 4 = 32. Since 20 < 32, 5 x 4 is less than 8 x 4.


9 x 4 = 36 and 6 x 4 = 24. Since 36 > 24, 9 x 4 is more than 6 x 4.


Each pair (one box of 3 + one box of 4) gives 3 + 4 = 7 cupcakes. With 4 boxes of each: 4x3 + 4x4 = 12 + 16 = 28. That is 4 + 4 = 8 boxes altogether.


324 + 50 = 374. The two numbers from the set that add to 374 are 324 and 50.

1 whole is 7/7. 7/7 - 4/7 = 3/7, so 4/7 and 3/7 make 1 whole. The answer is option (3).


For unit fractions, the larger the denominator the smaller the fraction. 1/7 has a bigger denominator than 1/6, so 1/7 < 1/6. The answer is option (1).


Adding like fractions: keep the denominator and add the numerators. 6 + 3 = 9, so 6/12 + 3/12 = 9/12. The answer is option (2).


Subtracting like fractions: keep the denominator and subtract the numerators. 8 - 2 = 6, so 8/9 - 2/9 = 6/9. The answer is option (4).
