Final answer:
To convert inches to feet, divide the number of inches by 12. Round the answer to the nearest tenth.
Step-by-step explanation:
To convert a child's height from inches to feet, divide the number of inches by 12. In this case, the child's height is 57.4 inches, so when we divide it by 12, we get 4.78 feet. To round it to the nearest tenth, we look at the digit after the tenths place, which is 8 in this case. Since 8 is greater than or equal to 5, we round the tenths place up. Therefore, the height of the child is approximately 4.8 feet.
