So for number 3, so for every 15 he earns, he saves 6 so 15:6=5:2
then he earns 75 and saves x 5 times what=75 5 times 15=75
2 times 15=30 so the ration is 75:30 he saved $30
then
write a real life proportion so rob has a pattern to make, for every 5 blue tiles, he puts down, he must put down 7 green tiles, he needs to fill a sqare area that is 12 feet in legnth and width each tile is 1 foot how many blue tiles will he need so 5+7=12 area=12 times 12 area=144 so the number of tiles is 144 so blue=5/12 so 144 times 5/12=60 blue tiles
