3/7•d=9/14 in this Problem you want to find what d equals

sertanlavr [38]

→ Chapter : Fractions ←
≡ We know that:
⇔ $(\frac{a}{b}) \div (\frac{c}{d})=(\frac{a}{b}) \times (\frac{d}{c})$

≡ Solution:
⇒ $(\frac{3}{7}) \times (d)=\frac{9}{14}$
⇒ $d=(\frac{9}{14}) \div (\frac{3}{7})$
⇒ $d=(\frac{9}{14}) \times (\frac{7}{3})$
∴ $\boxed{\frac{3}{2}}$
