MTH 114 Lecture Notes - Lecture 35: Long Division, Leading Zero
Document Summary
Use place value of the last digit in the decimal as the denominator, and put the decimal"s digits in the numerator. Canceling factors in multiplication; expressing proportions that do not have clean decimal equivalents (such as 1/7) When is it best to use decimals/percents? addition/subtraction; estimating results; comparing sizes; (b/c basis of comparison is equivalent since there is no denominator). Prefer decimals and percents for addition/subtraction, estimating numbers, or comparing numbers. Step 1: separate additional info from the actual question. Step 2: determine whether the question is value or yes/no. Step 3: decide exactly what the question is asking (one valuedefinitive yes or no) Step 4:use the grid to evaluate the statements (ad bce) If a ds question asks for the relative value of two pieces of a ratio, any statement that gives the relative value of any two pieces of that ratio will be sufficient.
