Simplify: \((0.625 \div 2.5) + \left(\frac{5}{8} \times 2\right) = ?\)
1.5
Solve each bracket first.
\(0.625 \div 2.5 = 0.25\).
\(\frac{5}{8} \times 2 = \frac{10}{8} = 1.25\).
\(0.25 + 1.25 = 1.5\).
Hence, the value is 1.5.
Simplify:
\(\left(2\frac{1}{4} \times 1.6\right) + \left(1\frac{1}{3} \div 0.4\right)\)
If P = 0.3 × 0.3 + 0.03 × 0.03 - 0.6 × 0.03 and Q = 0.54, then \(\rm \frac{P}{Q}\) is equal to:
