Evaluate 3/7r + 5/8s when r = 14 and s = 8
emmasim [6.3K]

\frac{3}{7}*r + \frac{5}{8} *s

let us first plug the values of r and s here

r=14 and s=8

\frac{3}{7}*14 + \frac{5}{8} *8

Now here we can cancel 14 and 7 as 7*2 =14 , also we can cancel 8 and 8 as 8*1 is 8, so our simplified new form is:

\frac{3}{1}*2 + \frac{5}{1} *1

Now we can multiply 3*2 and 5*1

3*2 =6

5*1=5

Next we add the two numbers

6+5 =11

So this is how we get the answer 11
