What is the value of $\frac{7×4÷8}{5×25÷125}+\frac{5×4÷8}{8×4÷16}-\frac{7×4÷2}{8×7÷4} ?$
Answer & explanation
Correct answer: option 3
$\frac{7×4÷8}{5×25÷125}+\frac{5×4÷8}{8×4÷16}-\frac{7×4÷2}{8×7÷4} ?$
= \(\frac{3.5}{1}\) + \(\frac{2.5}{2}\) - 1
= 3.5 + 1.25 - 1
= 4.75 - 1
= 3.75 = \(\frac{15}{4}\)
