Directions: Give the missing number/s in the equations below.
Answer:
1) 9 x 14=14 x 9
2) (11 x 5) x 10=11 x (5 x 10)
3) 3 x (12 + 5)=(3 x 12) + (3 x 5)
4) 12 x 11=33 x 4
5) 26 + 44 + 20=65 + 25
Solution:
1) 9 x 14=14 x 9
126=126
2) (11 x 5) x 10=11 x (5 x 10)
(55) x 10=11 x (50)
550=550
3) 3 x (12 + 5)=(3 x 12) + (3 x 5)
3 x (17)=(36) + (15)
51=51
4) 12 x 11=33 x 4
132=132
5) 26 + 44 + 20=65 + 25
(70) + 20=90
90=90
Directions: Find the missing terms in the equations below.
Answer:
1) 5 + (12 + 23)=(5 + 12) + 23
2) 15 x 7=7 x 15
3) 7 x (14 + 8)=(7 x 14) + (7 x 8)
4) 45 + 34 + 26=30 + 75
5) (15 x 5) x 4=15 x (5 x 4)
Solution:
1) 5 + (12 + 23)=(5 + 12) + 23
5 + (35)=(17) + 23
40=40
2) 15 x 7=7 x 15
105=105
3) 7 x (14 + 8)=(7 x 14) + (7 x 8)
7 x (22)=(98) + (56)
154=154
4) 45 + 34 + 26=30 + 75
(79) + 26=105
105=105
5) (15 x 5) x 4=15 x (5 x 4)
(75) x 4=15 x (20)
300=300
