Final answer:
To compare 5.43 and 5.6, we compare the digits in each decimal from left to right. The tenths digit in 5.6 is greater than the tenths digit in 5.43, so 5.6 is greater.
Step-by-step explanation:
To determine which decimal is greater, we compare the digits in each decimal from left to right. Both 5.43 and 5.6 have the same tens digit (5). Since the tenths digit in 5.6 (6) is greater than the tenths digit in 5.43 (4), we can conclude that 5.6 is greater than 5.43.
