Final answer:
The correct way to write out the proportion 7/28 = 2/8 in words is 'Seven twenty-eighths is equal to two eighths.' This is based on understanding that one eighth of a number is the same as dividing the number by 8.
Step-by-step explanation:
The correct option to write out the proportion 7/28 = 2/8 in words is option A, which states "Seven twenty-eighths is equal to two eighths."
To understand this, consider that when finding one eighth of a number, you are dividing the number by 8.
For example, one eighth of 1,000 is found by multiplying 1,000 by the reciprocal of 8, which is 1/8, resulting in 125. In simpler terms, if you were to split 1,000 into 8 equal parts, each part would be 125.
