$\frac{10\times 11}{10+11}$

that is the quick way i can explain the long way if you like, but that will be what we will get

3. anonymous

so how would you figure out the answer from this

4. anonymous

you mean how did i arrive at what i wrote, or how do you compute it?

5. anonymous

i get $\frac{110}{21}$ or as a decimal $$5.2$$ rounded

6. anonymous

i can derive that answer for you if that is what you are asking
