If you take the original ratio stated above, 12:360 (12 houses for every 360 weeks) and divide both sides of the ratio you get 1:30 (1 house every 30 weeks). You can take this ratio and multiply both sides by 7 to figure out how long it would take to build 7 houses. The final ratio is 7:210 (7 houses every 210 weeks)
Please give brainliest.
