Question

$$\frac{L72}{23}\div\frac{14}{29}; 6\frac{27}{27}\div\frac{16}{9}; \frac{622}{25}\times4; 0\frac{12p}{121}\frac{-6p}{b^{4}}$$

Answer

$$L*7223/1429;(209/9)/(16/9);622/25*4;0*(12*p)/121*-(6*p)/b^4$$

Solution


Simplify  \(\frac{627}{27}\)  to  \(\frac{209}{9}\).
\[\begin{aligned}&L\times \frac{7223}{1429}\\&\frac{\frac{209}{9}}{\frac{16}{9}}\\&\frac{622}{25}\times 4\\&0\times \frac{12p}{121}\times \frac{-6p}{{b}^{4}}\end{aligned}\]
Move the negative sign to the left.
\[\begin{aligned}&L\times \frac{7223}{1429}\\&\frac{\frac{209}{9}}{\frac{16}{9}}\\&\frac{622}{25}\times 4\\&0\times \frac{12p}{121}\times \frac{-(6p)}{{b}^{4}}\end{aligned}\]
