Estimate and then find the product of 12*5.2

12 x 5.2

Estimate:

since 5.2 is about 5, we can estimate this to:

12 x 5 = 60

Find the Product:

12

x 5.2

2 4

+ 6 0 0

6 2 4

now add the decimal back in. In the original problem there is one decimal place (the. 2 in 5.2) so we move the decimal place one over in our product

624 becomes 62.4
