Question

Your friend Iggy tells you that the product of 80 and 700 will have four zeroes. Explain to Iggy why his estimation is incorrect, and how to fix it.

Answer 1

Because 80 x 700 is 56000 and 56000 has 3 zeros not 4, make it so that she says 3 zeros 

Answer 2

Answer:

80 × 700 = 56000

Step-by-step explanation:

Iggy is absolutely wrong. The product of 80 and 700 simply means one should multiply the two numbers. A simple technique to know the number of zero's when you multiply two numbers is adding the numbers of zero of the two multiplicand.

The multiplicands 80 and  700 has 1 and 2 zero's respectively . The total number of zero's is 3. Then, the product of 7 and 8 has no zero so definitely we only have the 3 zero's . The product of 8 and 7 is 56 . Therefore , we add only the 3 zero's to get 56, 000.

80 × 700 = 56000

The estimation is definitely incorrect.
