Video Solution

Solution Steps

00:00 Solve
00:03 Let's use the distributive law
00:07 Let's break down 12 into 10 plus 2
00:11 Multiply the outer term by each term in parentheses
00:14 Calculate each product separately and then sum
00:17 Let's use long multiplication
00:25 Let's use long addition
00:28 And this is the solution to the question

Step-by-Step Solution

We will use the distributive property of multiplication and split the number 12 we got into a sum of 10 and 2. This allows us to work with smaller numbers and simplify the operation

Reminder - The distributive property of multiplication actually allows us to split the larger term in a multiplication problem into a sum or difference of smaller numbers, which makes multiplication easier and gives us the ability to solve the problem even without a calculator

97×(10+2)= 97×(10+2)=

We will use the distributive property formula a(b+c)=ab+ac a(b+c)=ab+ac

97×10+97×2= 97×10+97×2=

We will solve according to the order of operations

970+97×2= 970+97×2=

We will use the distributive property of multiplication again and split the number 97 into a sum of 90 and 7. This allows us to work with smaller numbers and simplify the operation

970+2×(90+7)= 970+2×(90+7)=

We will use the distributive property formula again a(b+c)=ab+ac a(b+c)=ab+ac

970+90×2+7×2= 970+90×2+7×2=

We will solve according to the order of operations

970+180+14= 970+180+14=

1150+14=1164 1150+14=1164

Therefore the answer is option C - 1164.

And now let's see the solution of the problem centralized:
97×12=97×(10+2)=97×10+97×2=970+(90+7)×2=970+90×2+7×2=970+180+14=1150+14=1164 97×12= 97×(10+2)= 97×10+97×2= 970+(90+7)×2= 970+90×2+7×2= 970+180+14= 1150+14=1164

Answer

1164 1164
