Which equation provides the best estimate of the product of 229 and 3.22

Question

Two hundred times three equals six hundred
Two hundred times four equals eight hundred
Three hundred times three equals nine hundred
Two fifty times three equals seven fifty

Answer 1

To estimate the product of 229 and 3.22, we can round these numbers to make the calculations easier:

• 229 is approximately 230.
• 3.22 is approximately 3.

Now, we can calculate the product of the rounded values:

230 × 3 = 690

Next, let's analyze the provided equations to see which one comes closest to this estimate of 690:

1. Two hundred times three equals six hundred (200 × 3 = 600)
2. Two hundred times four equals eight hundred (200 × 4 = 800)
3. Three hundred times three equals nine hundred (300 × 3 = 900)
4. Two fifty times three equals seven fifty (250 × 3 = 750)

Among these options, the equation "Two fifty times three equals seven fifty (250 × 3 = 750)" is the closest to our estimate of 690.

Thus, the best estimate from the given options is:

Two fifty times three equals seven fifty (250 × 3 = 750).
