There are 1518 toffees for 4 girls. if each girl recives the same number of toffees will be left

Ok so, the first thing to do is divide 1518 by 4 because there are four girls which leaves us with 379.5 and they can’t have half of one each so we round that down to 379, which means the most they can all have if they must have same amount is 379 each. So now how many are left? Multiply 379 by 4 and you’ll get 1516 so there will be 2 left ;)

If you need me to explain better just ask

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
