Question

5. Using distributive property, simplify the following
(1 85 10 + 35 x 10
(W) 66 x 25 + 66 x 75
(ii) 4.36 x 25+ 64 x 25
(iv) 67 x 13 + 67 x 167 + 67 x 120
(v) 135 x 85
(vi) 49 202
(vii) 187 x 66 + 187 x 34 (viii) 284 x 49
(ix) 550 X 628 - 550 x 528
(x) 53 x 17 - 39 x 17 - 4 x 17​

Answer 1

1) (85 x 10) + (35 x 10)
= 850 + 350
= 1200

2) (66 x 25) + (66 x 75)
= 1650 + 4950
= 6600

3) (36 x 25) + (64 x 25)
= 900 + 1600
= 2500

4) (67 x 13) + (67 x 167) + (67 x 120)
= 871 + 11189 + 8040
= 20100

5) 135 x 85
= 11475

6) 49 x 202
= 9898

7) (187 x 66) + (187 + 34)
= 12342 + 6358
= 18700

8) 284 x 49
= 13916

9) (550 x 628) - (550 x 528)
= 345400 - 290400
= 55000

10) (53 x 17) - (39 x 17) - (4 x 17)
= [(901) - (663)] - (68)
= 238 - 68
= 170
