Question

plz help ( ;
use benchmarks to estimate the sum

3 over 5 + 3 over 17 = ?

a) 2
b) 1 over 2
c) 1
d) 0

Answer 1

so this is

\[\large \frac{3}{5} + \frac{3}{17}\]

right?

Answer 2

yes

Answer 3

well, if we're just estimating, then

3/5 = 0.6 is close to 1

and

3/17 = 0.176 is close to 0

so

(3/5) + (3/17) = 1 + 0 = 1 (based on the estimations above)

Answer 4

thanks
