This is called the one-fifth rule. There will be some occasions when the one-fifth rule seems too generous. If you feel that your confidence in the last significant figure of the measurement is greater than this‚ then of course it would be more appropriate to use‚ say one-tenth of the least count. Similarly‚ if your confidence in the last significant figure is lower‚ then you might use half the least count. At any rate‚ you should use good judgment in estimating the error. Always think in terms of having

PS Solution from Forums 2 1. Positive integer n leaves a remainder of 4 after division by 6 and a remainder of 3 after division by 5. If n is greater than 30‚ what is the remainder that n leaves after division by 30? (A) 3 (B) 12 (C) 18 (D) 22 (E) 28 How to approach this Problem? Positive integer n leaves a remainder of 4 after division by 6 --> --> 4‚ 10‚ 16‚ 22‚ 28‚ ... Positive integer n leaves a remainder of 3 after division by 5 --> --> 3‚ 8‚ 13‚ 18‚ 23‚ 28‚ ... - we

learners according to the CAPS document. Definition Price (2001)‚ state that place value refers to our base-ten system‚ where each digit in a number represents a partial amount‚ this amount is determined by the structure of the number and the position of the digit in the number. In the base-ten system the position of a digit represents its value‚ therefore each digit has its own value in relation to another written symbol. This concept can be very easy to understand or it can be very complex‚ it

multiplied by a power of 10 and must be between 1 and 10. Significant figures: The number of digits you quote when you write down the value of a quantity that has been measured with a degree of uncertainty. The smaller the number of significant figures quoted for a value‚ the smaller the uncertainty in that value. The significant figure is the number(s) that carry meaning to that particular range of digits. So in the figure 247300‚ the most significant number is 2 as it tells us the number is 2 thousand

but if a “1” is added the subtrahend (bottom number) it is considered adding 1. Until students had a firm grasp and a solid foundation applying this method‚ there is much room for error. This algorithm does not require regrouping like the multi-digit problems presented in Week 5. Regrouping does not occur within this method because there is no need to “borrow” a hundred or ten and move it over to the tens or ones place. The top numbers are increasing by tens and the bottom numbers are increasing

Move the decimal point two places to the left. In a percent‚ the decimal point would come at the end of the last number (for 75%‚ envision that it looks like 75.) Examples: 75% converts to .75 40% converts to .40 3.1% converts to .031 ✔Changing decimal or whole number to percent Change a decimal
