Studdy Solution

STEP 1

1. We are tasked with estimating the products of three multiplication problems.
2. Estimation involves rounding numbers to the nearest ten or hundred to simplify calculations.
3. The problems to estimate are: - $673 \times 28$ - $48 \times 38$ - $359 \times 52$

STEP 2

1. Estimate $673 \times 28$
2. Estimate $48 \times 38$
3. Estimate $359 \times 52$

STEP 3

Round each number in the multiplication problem $673 \times 28$ to the nearest ten.
- $673$ rounds to $670$ - $28$ rounds to $30$

STEP 4

Calculate the estimated product of the rounded numbers.
$670 \times 30 = 670 \times (3 \times 10) = (670 \times 3) \times 10 = 2010 \times 10 = 20100$

STEP 5

Round each number in the multiplication problem $48 \times 38$ to the nearest ten.
- $48$ rounds to $50$ - $38$ rounds to $40$

STEP 6

Calculate the estimated product of the rounded numbers.
$50 \times 40 = (5 \times 10) \times (4 \times 10) = 5 \times 4 \times 100 = 20 \times 100 = 2000$

STEP 7

Round each number in the multiplication problem $359 \times 52$ to the nearest ten.
- $359$ rounds to $360$ - $52$ rounds to $50$

STEP 8

Calculate the estimated product of the rounded numbers.
$360 \times 50 = (36 \times 10) \times (5 \times 10) = 36 \times 5 \times 100 = 180 \times 100 = 18000$
The estimated products are:
1. $673 \times 28 \approx 20100$
2. $48 \times 38 \approx 2000$
3. $359 \times 52 \approx 18000$
