14 × 30
15 × 28
20 × 21
There are infinitely many possible pairs. For example, 10 and 42 or 0.1 and 4200.
2 x 2 x 3 x 5 x 7
I am not sure if any two consecutive numbers can add up to an even number.
420=2x2x3x5x7
3 and 13.
To multiply two digit decimal numbers, multiply the numbers as you would without the decimals. To put the decimal in the answer, count the number of decimal places in the two numbers and put the decimal in the answer that many places to the left. For example: 5.12 x 6.35 = 32.5120. If the numbers were 51.2 x 63.5, the answer would be 3251.20.
2 and 210
2x210.
There are many possible answers. One such pair is 1 and -420.

420 = 2 x 2 x 3 x 5 x 7
When you multiply two numbers, you get the product
there are infinites answers since answers can include decimals. Ane xample is 21*10 or 0.5*420 etc
