Question

simplify the number 7/2+5/8:-3/4-1/2×5/2​

Answer 1

$\frac{7}{2} + \frac{5}{8} \div \frac{3}{4} + - \frac{1}{2} \times \frac{5}{2} \\ \\ = \frac{7 \times 8 + 5 \times 2}{16} \div \frac{3 \times 2 + 4 \times 1}{8} \times \frac{5}{2} \\ \\ = \frac{56 + 10}{16} \div \frac{6 + 4}{8} \times \frac{5}{2} \\ \\ = \frac{66}{16} \div \frac{10}{8} \times \frac{5}{2}\\ \\ = \frac{66}{16} \div \frac{50}{16} \\ \\ = \frac{66}{16} \times \frac{16}{50} \\ = \frac{66}{50} \\\\=\frac{33}{25}</p><p>$
