Decimal Multiplication and Measurement Ranges
When learning to calculate 5.4 times 0.24 step by step, it's essential to break down the process into manageable parts. First, we multiply 5.4 by 10 to eliminate decimals, giving us 54. Similarly, multiply 0.24 by 100 to get 24. Next, multiply these whole numbers: 54 × 24 = 1,296. Finally, divide by the total factor (1000) to get 1.296.
Definition: Decimal multiplication can be simplified by temporarily converting decimals to whole numbers, multiplying, then adjusting the decimal point in the final answer.
When we determine range of height measurements cm, we must consider measurement precision. For a measurement of 72 cm to the nearest centimeter, the actual value could be any number from 71.5 cm up to 72.5 cm. This range accounts for the measurement uncertainty inherent in rounding to the nearest whole number.
