Question

помогите пример решить ​

Answer 1

$\frac{5b}{8 {a}^{3} } = \frac{5b \times 3 {b}^{2} }{24 { a}^{3} {b}^{2} } = \frac{15 {b}^{3} }{ 24 {a}^{3} {b}^{2} }$

$\frac{7a}{3 {b}^{2} } = \frac{7a \times 8 {a}^{ 3} }{24 {a}^{3} {b}^{2} } = \frac{56 {a}^{4} }{24 {a}^{3} {b}^{2} }$

$\frac{1}{2ab} = \frac{1 \times 12 {a}^{2}b }{24 {a}^{3} {b}^{2} } = \frac{12 {a}^{2}b }{ 24 {a}^{3} {b}^{2} }$

$\frac{2}{ {a}^{2} {b}^{2} } = \frac{2 \times 24a}{ 24 {a}^{3} {b}^{2} } = \frac{48a}{ 24 {a}^{3} {b}^{2} }$
