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

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

Kenny types 280 words. How long did he <br> type for?<br> A.4<br> B. 5<br> C.6<br> D. 7

zlopas [31]

Are you sure you didn’t miss anything while writing the question?

Cause we have nothing to go off. Everybody types differently so there is no way for us to say how long he typed for, unless we were given aprox how many words he wrote in a minute or something
