Determine whether each product or quotient is resonable.If not resonable,find a resonable result.

1. 62.77(29.8)=187.0546
2.16.132/2.96=54.5

The numbers are correct except for the decimal places.
The first one looks like 60*30 or 1800, so determine where the decimal should be.
The second looks like 16/3 = 5.3, so figure where the decimal should be placed there too.

I have to estimate each quotient. Then I have to tell which method I used.And #1 says 195 divided by 4=50, but I don't know what method to use so can you please help me?

I really have no idea sorry!!!

You are simply rounding up. You want the division problem to be very easy when you estimate. You either go up or down with the divisor and the dividend and get them both to end in zero ideally. Unless you have a single digit, such as your case here. Which means you will only estimate the 195. You round the 195 to 200 then divide by 4 which gives you an answer of 50.

50

To determine whether each product or quotient is reasonable, let's analyze the given statements:

1. 62.77 x 29.8 = 187.0546:
The product, 187.0546, seems reasonable. However, we need to consider the significant figures. Since 62.77 and 29.8 both have four significant figures, the final answer should also have four significant figures. Therefore, an appropriate answer would be 187.1.

2. 16.132 / 2.96 = 54.5:
The quotient, 54.5, seems reasonable. Nonetheless, we need to ensure the correct number of decimal places. Since the division involves values with three decimal places, the result should have a maximum of three decimal places. Therefore, an appropriate answer would be 54.4.

Regarding the estimation problem of 195 divided by 4, you can either round up or round down the numbers to make the division easier. In this case, you rounded up 195 to 200 and then divided it by 4, resulting in 50. This is a reasonable estimation and can be considered as a valid approximation.

I hope this clarifies the reasonableness of the given products and quotients. Let me know if you need any further assistance.

To determine whether each product or quotient is reasonable, we need to evaluate if the calculated results match our estimation or expectations.

1. For the first calculation, 62.77 * 29.8, the estimated result using rounding would be approximately 60 * 30 = 1800. However, the actual calculated result is 187.0546, which is not reasonable. To find a reasonable result, we can adjust the decimal places. The nearest whole number result would be around 187. Therefore, a more reasonable result for this product would be 187.

2. For the second calculation, 16.132 / 2.96, the estimated result using rounding would be approximately 16 / 3 = 5.3. The actual calculated result is 54.5, which is not reasonable. To find a reasonable result, we can adjust the decimal places. The nearest whole number result would be around 55. Therefore, a more reasonable result for this quotient would be 55.

Regarding the third question about dividing 195 by 4, you can estimate by rounding the dividend, 195, to the nearest multiple of 10, which is 200. Then divide 200 by the divisor, 4, which gives you a quotient of 50. The method used here is rounding the dividend and performing the division.

In summary:
1. 62.77 * 29.8: The reasonable result is 187.
2. 16.132 / 2.96: The reasonable result is 55.
3. 195 / 4: The estimated reasonable result is 50 when rounding the dividend to 200 and dividing by 4.
