Explanation:

Sally mass = 70 kilograms

Dave mass = 170 pounds ≈ 77 kilograms

Sally's mass as a percentage of Dave's mass = (70/77)x100

Sally's mass as a percentage of Dave's mass ≈ 91 %

Answer:

91%.

Explanation:

We have been given that Sally has a mass of 70 kilograms and Dave weighs 170 pounds.

First of all, we will convert Sally's weight into pounds by multiplying 70 by 2.205 as:


\text{Sally's weight into lb}=70* 2.205


\text{Sally's weight into lb}=154.35

Now, we will find 154.35 is what percent of 170 as:


(154.35)/(170)* 100


0.90794* 100=90.794\%\approx 91\%

Therefore, Sally's weight is approximately 91% of Dave's weight.
