Lesly got 14 answers correctly.

  • Let the correct answers be C.
  • Let the incorrect answers be I.

Given the following data:

  • Total number of questions = 30 questions.
  • Ratio of C to I = 7 : 8
  • C to I = 7 + 8 = 15

To find the number of answers she got correctly;

[tex]C = \frac{7}{15}[/tex] × [tex]30[/tex]

[tex]C = 7[/tex] × [tex]2[/tex]

Correct answers, C = 14 answers

Therefore, Lesly got 14 answers correctly.
