Find the answer and show your steps. Use distributive property or other ways to solve.
1. 25×32×25
2. 7×125×88
3. 207×101
1. To solve 25×32×25, we can rewrite it as (25×32)×25 using the associative property.
25×32 equals 800, so the expression becomes 800×25.
Now, we can multiply 800 by 25:
800×25 = 20,000.
Therefore, 25×32×25 = 20,000.
2. To solve 7×125×88, we can use the associative property to group the numbers in any way we prefer.
Let's group 7 with 88 and multiply first:
7×88 = 616.
Now, we have 616×125.
To find this product, we can use the commutative property to rearrange the numbers:
616×125 = 125×616.
Now, we can multiply 125 by 616:
125×616 = 77,000.
Therefore, 7×125×88 = 77,000.
3. To solve 207×101, we can use the distributive property.
Write 101 as 100+1.
Now, distribute 207 to both terms:
207×100 + 207×1.
Multiply each term separately:
207×100 = 20,700
207×1 = 207.
Add the two products together:
20,700 + 207 = 20,907.
Therefore, 207×101 = 20,907.
