1 answer

Let's solve each question step by step.

1. Find the product: 9.75 x 10^3

To find the product, simply move the decimal point in 9.75 three places to the right (because 10^3 is 1000).

9.75 x 1000 = 9750

Answer: 9,750


2. Find the sum: 68.47 + 121.35

Perform the addition:

68.47

  • 121.35

189.82

Answer: 189.82


3. There are 32 fish tanks in a pet store and no more than 18 fish in each tank. What is the greatest possible number of fish in the store?

To find the greatest possible number of fish, multiply the number of tanks by the maximum number of fish per tank:

32 tanks x 18 fish/tank = 576 fish

Answer: 576


4. Find the difference: 81.20 - 38.98

Perform the subtraction:

81.20

  • 38.98

42.22

Answer: 42.22


5. Estimate the product by rounding each number to the nearest whole number.

To round, we consider the whole number values of 9.75 and 10.

9.75 rounds to 10. 10^3 is already a whole number (1000).

So, estimating:

10 x 1000 = 10,000

Answer: 10,000
