How to interpret the fraction?
Suppose the fraction is proper (the numerator is smaller than the denominator).
Let it be
[tex]\dfrac{a}{b}[/tex]
Then, we can interpret it as:
a parts out of b parts of a thing.
[tex]1. \dfrac{2}{5} t = 20\\\\t = 20 \times \dfrac{5}{2}\\\\t= 50[/tex]
[tex]2. \frac{7}{8} p = 56\\\\p = 56 \times \frac{8}{7} \\\\ p= 64[/tex]
[tex]3. \frac{5}{6} x = 30 \\\\x = 30 \times \frac{6}{5} = 36[/tex]
[tex]4. \frac{1}{2} x = 20\\\\x = 20 \times 2 = 40[/tex]
[tex]5. \frac{3}{5} s = 60\\\\s = 60 \times \frac{5}{3} = 100[/tex]
[tex]6. \frac{1}{3} t = 3 \\\\t = 3\times 3 = 9[/tex]
[tex]7. \frac{3}{4} x = 9\\\\x = 12[/tex]
[tex]8. \frac{11}{12} x = 11\\\\x = 11 \times 12/11 = 12[/tex]
[tex]9. \frac{8}{10} t = 80\\\\t = 80 \times 10/8 = 100[/tex]
[tex]10. \frac{p}{3} = 9 \\\\p = 9 \times 3 = 27[/tex]
[tex]11. \frac{n}{5} = 30\\\\n = 30 \times 5 = 150[/tex]
[tex]12. \frac{6a}{7} = 36 \\\\a = 36 \times 7/6 = 42[/tex]
[tex]13. \frac{1}{2} t + 3 = 28\\\\t = (28 - 3)2 = 50[/tex]
[tex]14. \frac{1}{6} r = 12\\\\r = 12\times 6 = 72[/tex]
[tex]15. \frac{11}{12} b = 32\\ \\b = 32 \times 11/12 = 29.33[/tex]
