9514 1404 393

Answer:

8 people

Step-by-step explanation:

If 20 of 140 people play tennis, then in a group of 504 people, we expect ...

(20/140) × 504 = 72 . . . . tennis players

If 1 of 9 tennis players has a coach, then in a group of 72 tennis players, we expect ...

(1/9) × 72 = 8 . . . . have a coach

We expect 8 of the 504 people have a tennis coach. We made this prediction by applying the given rates to the larger group.

Answer:

0.04 can be written as $\frac{1}{25}$

Step-by-step explanation:

We have given the the quotient as 0.04

We have to write the expression which gives the quotient as 0.04

We know that 0.04 can be written as 4 x $10^{-2}$

We know that $10^{-2}$ = $\frac{1}{100}$

So 0.04 as quotient can be written as expression which has same value as 0.04
