Answer:
(a) Using distributive property of multiplication over addition,
786×84 + 786×16
= 786 × (84+16)
= 786 × 100
= 78600
(b) Using distributive property of multiplication over addition,
242×102
= 242 × (100+2)
= (242×100) + (242×2)
= 24200+484
= 24684
(c) By suitable rearrangement,
4×821×25
= 821×(4×25)
= 821×(100)
= 82100
(d) Using distributive property of multiplication over subtraction,
741×124 ‐ 741×24
= 741 × (124 ‐ 24)
= 741 × (100)
= 74100
(e) Using distributive property of multiplication over addition,
370×6+370×3+370
= 370×6+370×3+370×1
= 370×(6+3+1)
= 370×10
= 3700
(f) Using distributive property of multiplication over subtraction,
998×126
= 126×(1000-2)
= (126×1000) - (126×2)
= 126000 - 252
= 125748
Answer:
a) 786×84+786×16
786x (84+16)
786 x 100 = 78600
b) 242 x102
(242 x100) + (242 X2)
24200 + 844 = 25044
4×821×25
821 X (25X4)
821 X100 = 82100
d). 741×124–741×24
741 X (124-24)
741 X 100 = 74100
370×6+370×3×370
370 X (6+3)
370 X 9=
