Question

(4 1/2)^3*1.8^2 ------------------- (1 4/5)^3

Answer 1

$frac{(4frac{1}{2})^{3}cdot1,8^{2}}{(1frac{4}{5})^{3}}=frac{(frac{9}{2})^{3}cdot1,8^{2}}{(frac{9}{5})^{3}}=frac{frac{729}{8}cdot3frac{24}{100}}{frac{729}{125}}=$$frac{729}{8}cdotfrac{324}{100}}:frac{729}{125}=frac{729}{8}cdotfrac{324}{100}}cdotfrac{125}{729}=frac{405}{8}=50frac{5}{8}=50,625$
