This weekend Karen participated in a road race the ratio of the number of miles she ran to the number of miles she walked is 4 : 5 how many miles did Karen run if she walked 10 miles
If Karen ran 4 miles and walked 5 the fraction for that is 4/5 and if you double both of those you get 8/10 we know that she walked 10 miles so she had to have run 8 miles.
