Evaluate: 9695 + 765 =
- A.
10000
- B.
10010
- C.
10460
- D.
10572
Correct Answer
C. 10460Explanation
To evaluate the sum of 9695 and 765, we add the corresponding digits starting from the rightmost place value. Adding 5 and 5 gives us 10, so we write down 0 and carry over 1. Adding the next digits, 9, 6, and 6, gives us 21. Adding the carried over 1, we get 22. We write down 2 and carry over 2. Finally, adding the remaining digits, 9 and 7, along with the carried over 2, we get 18. Therefore, the sum of 9695 and 765 is 10460.Rate this question:

(a) Round off 386457 to the nearest ten thousand =
- A.
386457
- B.
390000
- C.
380000
Correct Answer
B. 390000Explanation
To round off 386457 to the nearest ten thousand, we need to look at the digit in the ten thousand place, which is 8. Since the digit to the right of 8 is 6, which is greater than or equal to 5, we need to round up. Therefore, the ten thousand place becomes 9, and all the digits to the right of it become zeros. Hence, the rounded off value of 386457 to the nearest ten thousand is 390000.Rate this question:

- A.
77
- B.
76
- C.

(a) Convert 3 6/100 as a decimal =
- A.
6.30
- B.
3.06
- C.
6.300
- D.

Correct Answer
B. 3.06Explanation
To convert a mixed number to a decimal, we first convert the fraction part to a decimal by dividing the numerator (6) by the denominator (100). This gives us 0.06. Then, we add the whole number part (3) to the decimal part, resulting in 3.06. Therefore, the correct answer is 3.06.Rate this question:

- C.
7/3
- D.
7 3/10
Correct Answer
D. 7 3/10Explanation
The given decimal number 7.3 can be converted to a mixed number fraction by separating the whole number part and the decimal part. The whole number part is 7 and the decimal part is 0.3. Since 0.3 can be written as 3/10 (where the numerator is 3 and the denominator is 10), the fraction form of 7.3 is 7 3/10.Rate this question:
