mina says that if you know the products up to 10x10, you also know the division facts up to a dividend of 100. is she right? Explain
Yes. How would you explain it?
Yes, Mina is right. Knowing the multiplication facts up to 10x10 does indeed help you know the division facts up to a dividend of 100.
To understand why this is true, let's first clarify what we mean by multiplication and division facts. Multiplication facts refer to the results of multiplying two numbers together, such as 3x4=12. On the other hand, division facts refer to the results of dividing a number by another number, such as 12÷3=4.
When we say that knowing the multiplication facts up to 10x10 helps us know the division facts up to a dividend of 100, it means that we can use our knowledge of multiplication to find the corresponding division facts.
For example, let's consider the multiplication fact 7x8=56. If we know this fact, we can use it to find the corresponding division fact by reversing the operation. So, we divide 56 by 7, which gives us 8. Therefore, the division fact is 56÷7=8.
Now let's think about the division facts up to a dividend of 100. The highest possible dividend we could encounter is 100. To find the division facts for this dividend, we need to know the corresponding multiplication facts that result in 100.
The highest possible multiples of two factors that give a product of 100 are 10 and 10 (10x10=100). So, if we know the multiplication fact 10x10=100, we can use it to find the division fact 100÷10=10.
In summary, knowing the multiplication facts up to 10x10 allows us to find the corresponding division facts up to a dividend of 100. By using our knowledge of multiplication, we can easily reverse the operation to find the division fact.
