Question

Estimate the difference to the nearest tenth.

0.8 – 0.638
A) 1.3
B) 0.13
C) 0.2
D) 0.1

Answer 1

C) 0.2

Explanation:

To estimate the difference between 0.8 and 0.638 to the nearest tenth, we can simply subtract the two numbers and round the result to the nearest tenth.

0.8 - 0.638 = 0.162

Rounding 0.162 to the nearest tenth gives us:

0.2

Therefore, the estimated difference between 0.8 and 0.638 to the nearest tenth is 0.2.

Answer 2

To estimate the difference between 0.8 and 0.638 to the nearest tenth, we need to subtract 0.638 from 0.8:

• 
  `0.8 - 0.638 = 0.162`

To round this to the nearest tenth, we look at the tenths place, which is 6. Since 6 is greater than 5, we need to round up. Therefore, the answer is:

• 
  `0.8 - 0.638 \approx \fbox{0.2}`
