Question

Aflati numarul stiind ca:
a) 8/9 din el constituie 24
b) 3/2 din el constituie 15

Va rog ajutati-ma!!

Answer 1

$\frac{8}{9} \times x = 24 \\ \frac{8x}{9} = 24 \\ 8x = 24 \times 9 \\ 8x = 216 \\ x = 216 \div 8 \\ x = 37$

$\frac{3}{2} \times x = 15 \\ \frac{3x}{2} = 15 \\ 3x = 30 \\ x = 30 \div 3 \\ x = 10$
