Estimate the product of two decimal numbers rounded to the nearest whole number. $4.8 \times 4.2 \approx \square$

STEP 1

Assumptions
1. The factors are 4.8 and 4.2
2. We need to round each factor to the nearest whole number before multiplying

STEP 2

First, we need to round each factor to the nearest whole number.
Let's start with 4.8. Since 4.8 is closer to 5 than it is to 4, we round it up to 5.
$4.8 \approx 5$

STEP 3

Next, we round 4.2 to the nearest whole number. Since 4.2 is closer to 4 than it is to 5, we round it down to 4.
$4.2 \approx 4$

STEP 4

Now that we have rounded each factor to the nearest whole number, we can multiply them together to estimate the product.
$Product = Rounded\, factor\, 1 \\times Rounded\, factor\, 2$

STEP 5

Plug in the rounded values for the factors to calculate the product.
$Product = 5 \\times 4$

STEP 6

Calculate the estimated product.
$Product = 5 \\times 4 = 20$
The product is approximately 20.

Estimate the product of two decimal numbers rounded to the nearest whole number. 4.8×4.2≈□4.8 \times 4.2 \approx \square4.8×4.2≈□

STEP 1

Assumptions1. The factors are 4.8 and 4.22. We need to round each factor to the nearest whole number before multiplying

STEP 2

First, we need to round each factor to the nearest whole number. Let's start with 4.8. Since 4.8 is closer to 5 than it is to 4, we round it up to 5.4.8≈54.8 \approx 54.8≈5

STEP 3

Next, we round 4.2 to the nearest whole number. Since 4.2 is closer to 4 than it is to 5, we round it down to 4.4.2≈44.2 \approx 44.2≈4

STEP 4

Now that we have rounded each factor to the nearest whole number, we can multiply them together to estimate the product.Product=Rounded factor 1timesRounded factor 2Product = Rounded\, factor\, 1 \\times Rounded\, factor\, 2Product=Roundedfactor1timesRoundedfactor2

STEP 5

Plug in the rounded values for the factors to calculate the product.Product=5times4Product = 5 \\times 4Product=5times4

STEP 6

Calculate the estimated product.Product=5times4=20Product = 5 \\times 4 = 20Product=5times4=20The product is approximately 20.
