First round to the nearest whole number.

9.86 x 9.13

Use compatible numbers to estimate each quotient.
32.2 divided by 7.56

Hello Ms. Sue! How do you round do the nearest whole number on the first one? Also how do you find compatible numbers to estimate the quotient?

Compatible numbers are numbers you can work in your head.
32,2 = 32
7.56 = 8

32/8 = ?

To find the product of 9.86 and 9.13 and round to the nearest whole number, you can multiply the two numbers together and then round the result. Here's how you can do it:

9.86 x 9.13 = 89.9958

Since we want to round to the nearest whole number, we can look at the decimal part of the number. In this case, the decimal part is .9958. Since the decimal part is greater than or equal to .5, we round up to the next whole number. Therefore, rounding 89.9958 to the nearest whole number gives us 90.

So, the answer is 90.

Now let's move on to the second question:

To estimate the quotient of 32.2 divided by 7.56 using compatible numbers, you can find two numbers that are close to the original numbers and that are easy to divide mentally. Here's how you can do it:

Look for two numbers that are close to 32.2 and 7.56. In this case, we can use 32 and 8 as compatible numbers.

32 divided by 8 is equal to 4.

So, we can estimate that 32.2 divided by 7.56 is roughly equal to 4.

Remember, using compatible numbers for estimation can help you quickly and mentally arrive at an approximate answer. The actual answer might be slightly different, but it provides a good estimation.

What don't you understand about these two problems?
