635 students are able to ignore distractions by others.

Explanation:

Since 45% are distracted by the talking, that means that 55% are able to ignore the distractions

58% of 1,095
$0.58 \cdot 1095 = 635.1$

You have to work out 58% of $1 , 095$ (the number of teens able to ignore distractions).

Explanation:

Work out 42% of $1 , 095$:

40%= 40/100 * 1,095 = 438

2%= 2/100 * 1,095 = 21.9

$438 + 21.9 = 459.9$

So

$1095 - 459.9 = 635.1$

teens, but because you can't have $.1$ of a teen, you have to round it down to $635$.
