Framing in equation form we get;
So, the number of remaining volunteers who donated blood =
.
Each of these volunteers donated blood = 470 ml
Now Total Amount of Blood donated is equal to Amount each of these volunteers donated blood times the number of volunteers who donated blood.
Framing in the equation form we get;
total amount of blood donated milliliters = 
Hence the equation representing total amount of blood donated is
.
Answer:
5/12
Step-by-step explanation:
1. Convert 1/4 to 3/12, then convert 1/3 to 4/12
2. Then add 3/12 and 4/12 together, which would be 7/12
3. Then subtract 12/12 by 7/12 which would be 5/12
So, 5/12 is your answer.
Hope this helps
