Question

Express $\frac{(0.8\times 0.7)-(0.65\times 0.6)}{(0.65\times 0.6)-(0.62\times 0.6)}$ in the form of a fraction.

Answer 1

Multiply and divide the equation by 100

=$\frac{(8\times 7)-(6.5\times 6)}{(6.5\times 6)-(6.2\times 6)}$

=$\frac{(56-39)}{(39-37.2)}$

=$\frac{17}{1.8}$

=$\frac{170}{18}$

=$\frac{85}{9}$
