Plz check my work

8*8=64
9*9=81
7*8=56
7/21=3
8/32=32

Your last two are wrong.

You probably mean 21/7 = 3

What about the last one?

I think the last one is 32/8=4

Is it right?

Yes, that's right.

Let's check your work step by step:

1. 8 * 8 = 64: This is correct. When you multiply 8 by 8, you get 64.

2. 9 * 9 = 81: This is also correct. When you multiply 9 by 9, you get 81.

3. 7 * 8 = 56: This is correct as well. When you multiply 7 by 8, you get 56.

4. 7 / 21 = 3: This is not correct. When you divide 7 by 21, you should get a decimal value, not a whole number. Let's calculate it:

To divide 7 by 21, you can use long division:

_____
21 | 7

First, we check how many times 21 can be divided by 7. The answer is 0.

Now, we bring down the next digit (0) from the dividend (7), making it 70.

Next, we check how many times 21 can be divided by 70. The answer is 3.

So, the correct answer for 7 divided by 21 is 0.3333... (which is a repeating decimal).

5. 8 / 32 = 32: This is also incorrect. When you divide 8 by 32, you should get a decimal value, not a whole number. Let's calculate it:

To divide 8 by 32, you can use long division:

_____
32 | 8

First, we check how many times 32 can be divided by 8. The answer is 0.

Now, we bring down the next digit (0) from the dividend (8), making it 80.

Next, we check how many times 32 can be divided by 80. The answer is 2.

So, the correct answer for 8 divided by 32 is 0.25.

In summary, three out of five answers are correct. The incorrect answers are 7/21 = 0.3333... and 8/32 = 0.25.
