Explanation
The given question is asking for the product of 4 and 14. When these two numbers are multiplied, the result is 56.

Explanation
The given question is asking for the difference between 213 and 86. By subtracting 86 from 213, we get the result of 127.

Explanation
The given expression is 98 divided by 14. When we divide 98 by 14, we get the quotient as 7. Therefore, the correct answer is 7.

Explanation
The given expression 87 + 96 - 45 simplifies to 183 - 45, which equals 138.

Explanation
The given expression involves multiplication and division. To solve it, we first perform the multiplication: 84 multiplied by 32 equals 2688. Then, we divide the result by 12: 2688 divided by 12 equals 224. Therefore, the correct answer is 224.

Explanation
The given expression involves addition and subtraction of numbers. When we add 2391 and 619, we get 3010. Subtracting 234 from 3010 gives us the final result of 2776.

Explanation
The given expression is 145 - 267 + 188. To solve this expression, we start from left to right. Subtracting 267 from 145 gives us -122. Then, adding 188 to -122 gives us a final result of 66.

Explanation
The given expression involves addition and subtraction of decimal numbers. Adding 4.67 and 71.3 gives 75.97. Subtracting 19.231 from 75.97 gives 56.739. Therefore, the correct answer is 56.739.

Explanation
The answer to 2.5 multiplied by 0.25 is 0.625.

Explanation
The given expression involves subtraction and addition of decimal numbers. When we subtract 3.43 from 5.2, we get 1.77. Adding 1.123 to 1.77 gives us 2.893. Therefore, the correct answer is 2.893.

Explanation
The given expression is the sum of the improper fractions 2/3 and 3/5. To add these fractions, we need to find a common denominator, which in this case is 15. We then convert both fractions to have the same denominator: 2/3 becomes 10/15 and 3/5 becomes 9/15. Adding these fractions together gives us 19/15 as the final answer.

Explanation
The given expression is the sum of two fractions, 1/6 and 1/5. To find the sum, we need to find a common denominator. The least common multiple of 6 and 5 is 30. We can rewrite 1/6 as 5/30 and 1/5 as 6/30. Adding these fractions together gives us 11/30.

Explanation
The given expression represents the subtraction of two fractions. To subtract fractions, we need to have a common denominator. In this case, the common denominator is 45 (the least common multiple of 5 and 9). By converting 1/5 and 1/9 to have a denominator of 45, we get 9/45 and 5/45 respectively. Subtracting these fractions gives us 4/45. Therefore, the correct answer is 4/45.

Explanation
The given expression represents the multiplication of two fractions. To multiply fractions, we multiply the numerators together and the denominators together. In this case, multiplying 16/27 and 18/28 gives (16 x 18) / (27 x 28). Simplifying this further, we get 288 / 756, which can be reduced to its simplest form as 8/21.

Explanation
The given question is a multiplication problem, asking for the product of 36 and 25. The correct answer is 900, which is obtained by multiplying 36 by 25.

Explanation
The given calculation is the product of 125 and 248. When these two numbers are multiplied together, the result is 31000.

Explanation
The product of 15 multiplied by 126 is equal to 1890.

Explanation
The given multiplication problem is 652 multiplied by 999. The product of these two numbers is 651,348.

Explanation
The given multiplication problem is 132 multiplied by 25. When we multiply 132 by 25, we get the product of 3300.

Explanation
The calculation of 864 multiplied by 125 results in the answer of 108,000.

Explanation
The correct answer to the multiplication of 64 and 96 is 6144. This can be calculated by multiplying the tens digits of both numbers (6 x 9 = 54) and writing down the units digit of the result (4). Then, multiply the units digit of the first number with the second number (4 x 6 = 24) and add the carry from the previous step (2). Finally, multiply the units digits of both numbers (4 x 6 = 24) and write down the result. Combining these results gives us 6144.

Explanation
The given multiplication problem is asking for the product of 117 and 113. When these two numbers are multiplied together, the result is 13,221.
