To determine the correct decimal representations of the fractions 5/8, 12/40, 2/5, and 3/16, each fraction must be converted to its decimal equivalent. Starting with 5/8, this fraction can be converted by performing the division: 5 divided by 8 equals 0.625. Next is 12/40. This fraction simplifies to 3/10, since both the numerator and denominator can be divided by 4. When converting 3/10, we arrive at 0.30. Then, for 2/5, dividing 2 by 5 gives us 0.40. Lastly, converting 3/16 entails dividing 3 by 16, which equals 0.1875. When rounded to two decimal places, this is 0.19. Thus, the decimal equivalents of the fractions are: - 5/8 = 0.625 (approximated to 0.63) - 12/40 = 0.30 - 2/5 = 0.40 - 3/16 = 0.19 The matching decimal array of these conversions is therefore 0.63, 0
