A clothing store has pants and shorts for sale in a ratio of 4:3. if there are a total of 70 pants and shorts available for sale, how many of those are shorts?
A 10
B 40
C 30
D 21
To find the number of shorts, divide the total number of pants and shorts by the ratio.
The ratio of pants to shorts is 4:3, which means for every 4 pants, there are 3 shorts.
Therefore, the total number of sets of 4 pants and 3 shorts is 70 divided by the common factor of 4 and 3, which is 7.
Now, multiply 7 by 3 to find the number of shorts: 7 * 3 = <<7*3=21>>21 shorts.
Therefore, the answer is D) 21.
