Solution____________
1,532-176=
estimate:_____ can you please show the work too thanks!!
Solutionz:____
214 = 200
182 = 200
est. 200 + 200 = 400
sol. 396
1532 = 1500
176 = 200
est. 1500-200 = 1300
sol. 1356
52.2 x 39.7
To estimate the sum of 214+182, you can round each number to the nearest ten and then add them together.
214 rounds to 210, and 182 rounds to 180.
Now, add 210 and 180:
210 + 180 = 390
So, the estimated sum of 214+182 is 390.
To find the exact solution, simply add the numbers together:
214 + 182 = 396
Therefore, the exact sum of 214+182 is 396.
Now, let's move on to the second question.
To estimate the difference of 1,532-176, you can again round each number to the nearest ten and then subtract them.
1,532 rounds to 1,530, and 176 rounds to 180.
Now, subtract 180 from 1,530:
1,530 - 180 = 1,350
So, the estimated difference of 1,532-176 is 1,350.
Now, to find the exact solution, simply subtract the numbers:
1,532 - 176 = 1,356
Therefore, the exact difference of 1,532-176 is 1,356.
Please note that the estimated answer is an approximation, while the exact solution provides the precise result.
