- What is the sum of 367 and 284?
A.641 B.651 C.661 D.671
Answer:B
Rationale:Add 367 + 284: Ones (7 + 4 = 11, write 1, carry 1), tens (6 + 8 + 1 = 15, write 5, carry 1), hundreds (3 + 2 + 1 = 6). Result is 651. A, C, and D are incorrect due to carrying errors.
- Subtract 493 from 628.
A.125 B.135 C.145 D.155
Answer:B
Rationale:Subtract 628 − 493: Ones (8 − 3 = 5), tens (2 − 9 requires borrowing, 12 − 9 = 3), hundreds (5 − 4 = 1). Result is 135. A, C, and D are incorrect due to borrowing errors.
- Multiply 17 by 23.
A.381 B.391 C.401 D.411
Answer:B
Rationale:Multiply 17 × 23: 17 × 3 = 51, 17 × 20 = 340, sum 51 + 340 = 391.Alternatively, 17 × (20 + 3) = 340 + 51 = 391. A, C, and D are incorrect due to multiplication errors.
- Divide 624 by 16.
A.37 B.38 C.39 D.40
Answer:C
Rationale:Divide 624 ÷ 16: 16 × 39 = 624 (16 × 30 = 480, 16 × 9 = 144, 480 + 144 = 624). No remainder. A, B, and D yield incorrect quotients.
- Add 4.72 and 3.19.
A.7.81
B.7.91
C.8.01
1 1 / 2
D.8.11
Answer:B
Rationale:Align decimals: 4.72 + 3.19 = 7.91 (ones: 4 + 3 = 7, tenths: 7 + 1 = 8, hundredths: 2 + 9 = 11, write 1, carry 1). A, C, and D are incorrect due to carrying errors.
- Subtract 9.45 from 15.82.
A.6.27
B.6.37
C.6.47
D.6.57
Answer:B
Rationale:Subtract 15.82 − 9.45: Ones (5 − 9 requires borrowing, 15 − 9 = 6), tenths (7 − 4 = 3), hundredths (2 − 5 requires borrowing, 12 − 5 = 7). Result is 6.37.A, C, and D are incorrect.
- Multiply 0.7 by 0.4.
A.0.28
B.0.32
C.0.36
D.0.40
Answer:A
Rationale:Multiply 0.7 × 0.4 = 0.28 (7 × 4 = 28, two decimal places). Alternatively, 7/10 × 4/10 = 28/100 = 0.28. B, C, and D are incorrect due to decimal errors.
- Divide 5.4 by 0.6.
A.8 B.9 C.10 D.11
Answer:B
Rationale:Divide 5.4 ÷ 0.6: Convert to 54 ÷ 6 = 9. Alternatively, 0.6 × 9 = 5.4.A, C, and D yield incorrect results.
- Convert
2 5 to a decimal.A.0.3 B.0.4 C.0.5 D.0.6
Answer:B
Rationale:Divide 2 ÷ 5 = 0.4. A, C, and D do not result from 2 ÷ 5.
- Convert 0.875 to a fraction in simplest form.
- / 2
A.7 8 B.3 4 C.5 6
