You know that 15% of a number n is 12. How can you use this to find 30% of n? 45% of n? Explain.

Because 30% of n is equal to [ ] times 15% of n and 45% of n is equal to [ ] times 15% of n, you can write

30% of n=[ ] ×12= [ ]

and

45% of n= [ ] ×12= [ ]
PLEASE HELP THIS IS VERY URGENT!!!

Respuesta :

Take the percentage that you want to find and divide it by 15
Take the number you get and multiply it by 12
Than 30% =24
45%=36
