Final answer:
To divide 7 by 2/1, multiply the numerator of the dividend by the reciprocal of the divisor. The answer is 7/2 or 3 and 1/2.
Step-by-step explanation:
To divide a whole number by a fraction, we convert the whole number to a fraction with a denominator of 1. In this case, 7 can be written as 7/1. Then, we multiply the numerator of the dividend (7) by the reciprocal of the divisor (1/2). So, 7 ÷ 2/1 becomes (7/1) × (1/2).
Multiplying the numerators (7 × 1 = 7) and the denominators (1 × 2 = 2), we get 7/2. The answer can be written as a whole number (3) with a remainder (1) or as a proper fraction (7/2), which is already in its simplest form.
