Answer:
It took her 4 hours to complete her homework
Step-by-step explanation:
Let x be the time taken to complete her homework
From the question, Annabelles homework is 75% complete and it took her 3 hours, this implies that;
75% of the homework done = 3hours
75% × x = 3
[tex]\frac{75}{100}[/tex] × x = 3
[tex]\frac{75x}{100}[/tex] = 3
Multiply both-side of the equation by 100
[tex]\frac{75x}{100}[/tex] × 100= 3×100
At the left-hand side of the equation, 100 will cancel-out 100
75x = 300
Divide both-side of the equation by 75
75x/75 = 300/75
x = 4 hours
