Question

Solve the proportion (w+12)/(3w+5)=3/4

Answer 1

`w=6.6`

`18.6:24.8::3:4`

Explanation:

`As\ we\ know\ that,\\(w+12):(3w+5)::3:4\\By\ the\ proportion\ method\ of\ multiplying\ the\ means\ and\ the\ extremes,\\we\ get,\\(w+12)*4=3*(3w+5)\\4w+48=9w+15\\48-15=9w-4w\\33=5w\\`

`w=33/5\\w=6.6`

`By\ substituting\ the\ value\ of\ w\ in\ the\ proportion. you\ get:\\(6.6+12)/(3*6.6+5)=3/4\\18.6/24.8=3/4\\18.6:24.8::3:4`
