To estimate 3/5 × 9 1/2, we can use the following three methods:
Method 1: Mental Calculation
To estimate using mental calculation, we can round the numbers to the nearest whole number before performing the multiplication. In this case, we can round 3/5 to 1 and 9 1/2 to 10. Now we can simply multiply 1 × 10, which gives us an estimate of 10.
Method 2: Rounding to Final Answers
In this method, we round each number individually and then perform the calculation. We can round 3/5 to 0.5 and 9 1/2 to 10. Finally, we multiply 0.5 × 10, which gives us another estimate of 5.
Method 3: Decimal Conversion
To estimate using decimal conversion, we can convert the fraction 3/5 into a decimal and then perform the calculation. 3/5 is equal to 0.6 as a decimal. Now we can multiply 0.6 × 9.5 to get an estimate of 5.7.
In summary:
Method 1: Mental Calculation - estimate of 10
Method 2: Rounding to Final Answers - estimate of 5
Method 3: Decimal Conversion - estimate of 5.7
Note that these are only estimations, and the actual product of 3/5 × 9 1/2 is 2.7.
