last month Dory biked 11 times as many miles as karly.Together theybiked a total of 156 miles.How many miles did Dory bike last month show all working.
It's a ratio of 11:1 So there are 12 parts in total So 156 ÷ 12 = 13 So 1 part of the ratio is 13miles You then want to times it by the 11 parts that Dory has so 13 × 11 is 143
