Final answer:
Maria must round her value to the nearest hundredth by checking the digit in the thousandths place; if it is 5 or greater, she rounds up, otherwise, she rounds down.
Step-by-step explanation:
Maria is trying to estimate a number to the nearest hundredth, which implies a level of precision that involves evaluating decimal points. When attempting to round a number such as 70 to the nearest hundredth, she should first consult her table of values to determine the points that fall directly before and after 70 in terms of their decimal values. It's important for Maria to round her final answer to the hundredths place, based on the precision of the data in her table. According to the mathematics rules for rounding, if a digit one place to the right of the hundredths place (the thousandths place) is 5 or greater, Maria needs to round up. If it's less than 5, she rounds down. For example, if her calculation resulted in a number like 201.867, she would round this to 201.87 because the 7 in the thousandths place necessitates rounding up. It's crucial that Maria pays attention to significant figures and the rules for rounding as outlined in various examples.
