7 x 420 = 7(400 + 20) = 7 * 400 + 7 * 20.
(7 x 60) + (7 x 5) = 420 + 35 = 455
The distributive property is a property that is relevant to two binary operations, not to numbers. 5(4 + 7)
7
8*37 = 8*(30+7) = 8*30 + 8*7 [that is using the distributive property] = 240 + 56 = 296
You could write 35*27 as (30+5)*(20+7) Using the distributive property with the first bracket as the multiplier (30+5)*20 + (30+5)*7 Then using the distributive propetrty twice gives 30*20 + 5*20 + 30*7 + 5*7 =600 + 100 + 210 + 35 = 945
The distributive property refers to a property of TWO binary operations - usually of multiplication and addition - not just one operation. Consequently, 7*420 does not have a distributive property.
7 x 420 = (7 x 400) + (7 x 20)
(7 x 60) + (7 x 5) = 420 + 35 = 455
7 x 86 does not HAVE a distributive property. The distributive property of multiplication can be used to calulate 7 x 86 as 7 x 86 = 7 x 80 + 7 x 6
7*14 = 98. Why does the distributive property need to come into it?
The distributive property is a property that is relevant to two binary operations, not to numbers. 5(4 + 7)
7
An expression equal to 15 + 35, using distributive property, is 5(3 + 7). Under distributive property, 5*3=15 and 5*7=35.
distributive
7 x 420 = (7 x 400) + (7 x 20)
The distributive property of multiplication over addition allows you to partition a multiplication problem into simpler chunks: For example: 4*57 = 4*(50+7) = 4*50 + 4*7 that last step used the distributive property = 200 + 28 = 228
8*37 = 8*(30+7) = 8*30 + 8*7 [that is using the distributive property] = 240 + 56 = 296
