for questions 1 and 2 chose the equation that you can use to solve the problem.
86 is 45% of what number
A( 86 = 0.45n
B( n=0.45 X 86
c( 0.45=n X 86
D( 86 = 45n
And your answer is?
To solve the equation "86 is 45% of what number," we can use equation B: n = 0.45 x 86.
To solve the problem, "86 is 45% of what number?", we need to choose the equation that represents this relationship.
The correct equation is:
A) 86 = 0.45n
Explanation:
