A pitcher struck out 11 out of 40 batters. Write an equivalent decimal.

Komok [63]

Answer:

0.275

Step-by-step explanation:

We want to write 11 out of 40 batters as a decimal.

We can write 11 out of 40 as a fraction to get:

$\frac{11}{40}$

Note that:

$\frac{11}{40} = \frac{1}{4} \times \frac{11}{10}$

This implies that:

$\frac{11}{40} = 0.25 \times 1.1$

This gives us

$\frac{11}{40 } = 0.275$
