475 = 400 + 70 + 5
therefore
9 × 475 = 9 × (400 +70 + 5) = 9 × 400 + 9 × 70 + 9 × 5
=3600 + 630 + 45 = 4275
I think... It's better to use Distributive Property:
(a - b) × c = a × c - b × c
9 = 10 - 1
therefore:
<span>(10 - 1) ×475 = 10 × 475 - 1 × 475 = 4750 - 475 = 4275</span>
To find out how many pounds<span> in </span>tons<span>, multiply by the right </span>conversion<span> factor or use the </span>converter<span> below to </span>convert<span> from short </span>tons. Enter a value that you want to convert<span> into </span>pounds<span> and click on the "</span>convert<span>" button. </span>Ton<span> is a unit of mass in different measurement systems and usually mistaken with each other.</span>
0.4 because if it’s five or more, add one more. If it’s four or less, let it rest.
