(echoing synth noise)… Here are the solutions to…Challenge Worksheet number seven.…If your answers do not match my answers, continue watching…this video and I will walk you step by step through…every problem.…Equation A is...…In order to begin solving this equation, we may want to…get rid of those decimals, so in order to do that…we need to think of a power of 10 that we can multiply…every term by in order to get rid of the decimals.…
When you take a look at this equation,…notice that we have three decimal places after the…decimal in this number and in this number.…And that's the largest, they both go out to the…thousandths place.…So because we need to make sure that we make these…two numbers whole numbers, we need to multiply every…single term by 1000.…So I'm going to show that I'm going to multiply the…lefthand side and the righthand side by 1000…so that I can eliminate those decimals.…
Now we're going to distribute 1000 throughout the…lefthand side.…Remember that when we multiply by 1000,…we can take the shortcut of just moving that decimal…
