A​ person's blood type is denoted with the letters​ A, B, and​ O, and the symbols​ + and - . The blood type​ A+ is read as A positive. The blood type B - is read as B negative. Use the data to write a ratio for the comparison in 3 different ways.

(a) O+ to A+

(b) AB- : AB+

(c): B+ to total

Step-by-step explanation:

Given

See attachment

Required

Solving (a): O+ to A+

We have:

So, the ratio is:

---- first comparison

Divide by 5

---- Second comparison

Divide by 45

---- Third comparison

Solving (b): AB- to AB+

We have:

So, the ratio is:

---- first comparison

Divide by 2

---- Second comparison

Multiply by 2

---- Third comparison

Solving (c): B+ to total

We have:

So, the ratio is:

---- first comparison

Divide by 5

---- Second comparison

Multiply by 2

---- Third comparison

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

the answer would be c:   ax + b = ax + c
