Estimate the product 552 × 82
- 48000
- 46000
- 45000
- 42000
Hint:
The estimate value are round up or down value of the actual value. The actual product is hard to do mentally and it takes time but when we take compatible number for estimation is easy to calculate mentally and saves time. Here we wants estimate product 552 x 82.
The correct answer is: 48000
Here we need to find the estimated product of 552 x 82.
Since ,the actual product of 552 x 82 is,
552 x 82 = 45,264
And it mentally hard to calculate the we are going to estimate this product and find the compatible numbers,
Now
552 → 600 , here the 552 is rounded up to 600.
And,
82 → 80, here 82 rounded down to 80 ,
Both number are compatible now the product of these numbers are,
600 x 80= 48000
Therefore, the estimated product of 62 x 87 is 600 x 80= 48000 .
The correct answer is 48000 .
The estimated product is the rounded product of actual product. Just find the compatible number and rounded up or down and the product is like mentally easy to solve. Apply same methods in similar questions.
