Make an estimate and solve the estimate problem 8.21×3.6

Answer 1

To estimate the product of 8.21 and 3.6, we can round each number to a simpler value:

• 8.21 can be rounded to 8.
• 3.6 can be rounded to 4.

Now we can multiply the rounded values:

\[ 8 \times 4 = 32 \]

So, the estimated answer for \( 8.21 \times 3.6 \) is approximately 32.

Now, let’s calculate the exact product:

\[ 8.21 \times 3.6 = 29.556 \]

Thus, the exact product is 29.556, and our estimate of 32 was close, but over the actual value.
