Answer:

(c) Clark

Explanation:

All of the weights have the same integer part (627), so you only need to compare the fractions.

You know that 0.4 is less than 0.6.

You also know that 3/8 = 6/16 is less than 7/16.

So, you only need to compare 3/8 and 0.4 to determine which is the smaller value.

Here, you can make use of your knowledge of decimal equivalents:

3/8 = 0.375

so 3/8 < 0.4 and the least weight listed is 627 3/8, Clark's weight.

Additional comment

It is useful to remember the decimal equivalents of fractions with small integer denominators. Here are some unit fractions to get you started:

1/2 = 0.5

1/3 = 0.33...(repeating)

1/4 = 0.25

1/5 = 0.2

1/6 = 0.166...(repeating 6)

1/7 = 0.142857...(6-digit repeat)

1/8 = 0.125

1/9 = 0.11...(repeating)

1/10 = 0.1

1/11 = 0.0909...(2-digit repeat)
