On a school trip to a theme park, four busses each carry 175 students. 45% of the students are bringing their own lunch. 3 7 of the students are buying lunch when they get to the theme park. The teachers are worried that some students have not made plans for lunch. Find how many students have not made plans for lunch.

348

Step-by-step explanation:

175(kids per bus) times 4(# of buses) =700

45% of 700 =315

so if you subtract 315 from 700 you get 385

then you subtract the kids who are buying lunch when they get there

385-37=348

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

you just switch the numbers basically so it would be 3/17
