Help me please i really need it I need solution.

30 are present and 10 are absent

Step-by-step explanation:

75% of 40 is 30

Therefore 30 pupils are present

And 10 pupils are absent

Step-by-step explanation:

1. To figure this out, you need to first convert the percentage to a decimal. To do this, you move the decimal two places back. 75.0% -> 0.75

40 * 0.75 = 30 students are present, because 75% of 40 is 30

40 - 30 = 10 students are absent, because 30 students are present.

2. To figure this out, you must do the same thing you did for number 1 above. It would look like this: 80% -> .80

250 * 0.8 = 200 euros - not sure if that's what it is but that is what I'm going with - is what she spent, because 80% of 250 is 200

250 - 200 = 50 is what she saved.
