Hi Safari;
1 pound = 453.59237 grams
In round figures...
1 pound = 454 grams
1 pound/454 grams = 1
(1 pound/454 grams)=(250 pounds/x grams)
Let's flip these...
(454 grams/1 pound)=(x grams/250 pounds)
Let's multiply both sides by 250 pounds...
250 pounds (454 grams/1 pound)=250 pounds (x grams/250 pounds)
Let's cancel words where appropriate...
250 pounds (454 grams/1 pound)=250 pounds (x grams/250 pounds)
Do you understand? pound(s)/pound(s)=1. Henceforth, these cancel.
Now we have...
250(454 grams)=250(x grams/250)
Let's cancel numbers where appropriate...
250(454 grams)=250(x grams/250)
Do you understand? 250/250=1. Henceforth, these cancel.
Now we have...
250(454 grams)=x grams
113500=x grams
I LOVE MATH! Thank you.
