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.
