@mephatboi the fraction was 1.25mol/0.25mL, he wants to make the denominator 1. So he multiplies the top and the bottom by 4. If he only multiplies the numerator then the result would be completely different. Same goes for the denominator. Hope this helps.

hey y u multiplied by 2?in Q 1?

[mephatboi]

ummmmm....... in ex. 1, u multiplied numerator AND denominator by 2 so that should say: 2/2 (not 2)???
