To estimate the product of 2/3 and 31, we can use rounding and mental math. Here's a step-by-step method to estimate the product:
Step 1: Round the decimal number (31) to the nearest whole number. In this case, 31 remains 31.
Step 2: Find an easy fraction that is close to 2/3 and has a denominator of 3. An easy fraction to work with is 1/3.
Step 3: Multiply the rounded whole number (31) by the fraction obtained in step 2 (1/3). This can be done by multiplying the numerator of the fraction (1) with the rounded whole number (31) to get the estimated answer.
Therefore, the estimated product of 2/3 and 31 is 31/3 or approximately 10.33.
Please note that this is an estimation and may not be an exact answer.
