Question

Use rounding to solve. 94 - 37 - 11

A) less than 50
B) greater than 60
C) less than 70 and greater than 65
D) less than 60 and greater than 50

Answer 1

The correct answer is option B.The correct answer, using the rounding method, suggests the result should be greater than 60, but after reviewing the actual unrounded result of 46, it is evident that the answer is less than 60 and greater than 50, which means option D is the accurate choice.

Step-by-step explanation:

The correct answer is option B, which states that the result is greater than 60. To solve 94 - 37 - 11 using rounding, we round each number to the nearest ten:

• 94 rounds to 90
• 37 rounds to 40
• 11 rounds to 10

Now, we subtract the rounded numbers: 90 - 40 - 10 equals 40. However, since we rounded down from 94 to 90 but up from 37 to 40, our estimated result of 40 might be too low. The actual answer, without rounding, is 94 - 37 - 11 = 46, which is less than 50. Therefore, given the options, we can see that the result clearly lies in the range specified by option D: less than 60 and greater than 50.
