Final answer:
To convert fractions to decimals, divide the numerator by the denominator. For 56/15, this is approximately 3.7 when rounded to the nearest tenth. For 18/19, it's about 0.95 when rounded to the nearest hundredth.
Step-by-step explanation:
To convert 56/15 and 18/19 to decimal form and round to the nearest tenth and nearest hundredth respectively, we'll divide the numerators by the denominators.
For 56/15, when we do the division, we get 3.7333.... Rounding this to the nearest tenth will give us 3.7.
For 18/19, we calculate the division to get 0.9473.... Rounding this to the nearest hundredth is done by looking at the third decimal place, which is a 7. Since this is more than 5, we round up to get 0.95.
Remember, the precise figures you use initially impact the precision of your final result. In the case of calculating significant figures or when adding and subtracting measurements, always use the least precise measurement to determine how to round your final answer.
