Answer 1

Hello!

${ \frac{7}{8} }x + { \frac{1}{2} } = { \frac{5}{16} } \times 4 \\ { \frac{7x}{8} } + { \frac{1}{2} } = { \frac{5 \times 4}{16} } \\ 7x + { \frac{8 \times 1}{2} } = { \frac{8 \times 20}{16} } \\ 2( 7x )+ 8 = { \frac{2 \times 160}{16} } \\ 16(14x + 8) = 320 \\ 224x + 128 = 320 \\ 224x = 192 \\ x = { \frac{192}{224} } = { \frac{6}{7} } =0.85714$
