During a blood drive, the ratio of Type O donors to non-Type O donors was 37:43. About how many Type O donors would you expect in a group of 300 donors?

258

Step-by-step explanation:

Type O: Non-Type O = 37:43

Now we just plug in values!

Type O:300 = 37:43

Now we will do some proportions. Remember that 300x37=Type Ox43, meaning that 11100/43 will give us our answer of 258.139534884, rounding to 258.

the answer is 0.3175 hope that you ^w^
