Asap and tell me how you did the work! ❤️❤️❤️ 360 is 90% of what number? 48 is 25% of what number? 63 is 30% of what number? 240 is 75% of what number?

To answer all of these you make a fraction and it is structured like this: is/of=percent/100. So if it is asking for the of and you don't know if you just multiply 100 by the is and divide it by the percent. But if it is asking for the is then you multiply the percent by the of and divide it by 100
1. 400, 360/x=90/100 so you multiply 360 by 100 and get 36000 and divide it by 90

(m+11n)^2=(m+11n)(m+11n)=m^2+11mn+11mn+121n^2=m^2+22mn×121n^2 for example; use foil: (a+b)(a+b)first. a^2outside. abinside. ablast. b^2
