(Draw a rectangle, break up the parts of the partial products, and add them together to get 64,083.

≈ 10,000 x 100 = 1,000,000 OR 10,000 x 120 = 1,200,000.

It's reasonable! You can round the factors to 200 x 800, but both factors rounded up, so your answer should be a bit less than 160,000.

We are working with hundredths, so: 33364 hundredths, or 333.64. (Or, think: a hundred times smaller--move the decimal to shift digits ÷10, ÷10.)

(Use the standard algorithm to get rows: 753 + 2510 + 50,200 = 53,463. Or 213 + 10,650 + 42,600 = 53,463.)

The factory produces 36 kilograms of candy in 1,000 minutes.

We are working with tenths, so: 33364 tenths, or 3,336.4. (Or, think: ten times smaller--move the decimal left one place value to shift digits ÷10.)
