Adding and subtracting fractions can ONLY be done if the denominators are the same; then the calculation is done by adding or subtracting the numerators. Multiplying (and dividing) fractions does not require the denominators to be the same. To divide by a fraction the divisor is inverted (the original numerator becomes the new denominator and the original denominator becomes the new numerator) and then the fractions are multiplied. Multiplying fractions is achieved by multiplying the numerators together AND multiplying the denominators together. A whole number is the same as a fraction with the whole number as the numerator and a denominator of 1, so when multiplying by a whole number the denominator is multiplied by 1 (leaving it the same) and the is multiplication is effectively just multiplying the numerator by the whole number.
1 multiplied by 5 plus 2 equals 7. This is because you are multiplying 1 into 5 and then adding 2.
That would be called the operations.
The missing numbers in the pattern can be found by multiplying the first number by 2, then adding 1 to get the second number, multiplying the second number by 2 and subtracting 1 to get the third number, and so on. Therefore, the missing numbers are 7 and 61.

The result of the given operations is 697.
The result of multiplying 27 by 1 and then adding 4 is 31.
The result of multiplying 32 by 630 is 20,160. Multiplying 27 by 1 gives 27. Adding 4 to the total gives a final result of 20,191.

To multiply binary numbers, follow these rules: Multiply each bit of the second number by each bit of the first number, starting from the right. Add the results while considering their positions. Carry over any "overflow" to the next bit. Remember that 0 x 0 = 0, 0 x 1 = 0, 1 x 0 = 0, and 1 x 1 = 1.
4 + 6 - 1 + 0 x 2 x 3 x 5 x 7 ÷ 8
The result of multiplying 32 by 630 and then adding the product of 27 multiplied by 1 and 1/4 is 20,160 33.75, which equals 20,193.75.
The result of multiplying 27 by 1 is 27. Adding 3 to 27 gives 30. Dividing 30 by 8 results in 3.75.
The question depends on what it is that you want to prove!
