Question

A factory makes 9,078 sheets of construction paper per hour. About how many sheets of construction paper will the factory make in 74 hours? Choose the better estimate.

• A. 6,30,000
• B. 6,00,000
• C. 7,00,000
• D. 6,50,000

Answer 1

The correct option is A 6,30,000

The general rule that we make is,
round off each factor to its greatest place, then multiply the rounded off factors.

Rounding off 9078 to nearest thousands gives 9000
Rounding off 74 to nearest tens gives 70
Therefore, the estimated product = 9000 x 70 = 6,30,000

Therefore, the number of sheets of construction paper the factory makes in 74 hours is 6,30,000 (approx).
