Writing basic expressions word problems

let's do a few examples of writing expressions to help us solve word problems so they tell a Suzy ran a race she ran five miles an hour and the race took her T hours to complete how long was the race write your answer as an expression all right if we're trying to figure out the number of miles you'd want to take her speed which is in miles per hour so five miles per hour times the number of hours so the number of hours is T so you could literally just write that as five T 5 T literally means 5 times T now another way you could have done it is you could have use this little dot symbol here this is not a decimal it's it's higher than a decimal and it means multiplication five times T either that either of these five dot T or five T means 5 times T it makes sense you take your speed times your time and you'll figure out how far you actually went check my answer here let's do a few more of these the running aces card team won five hundred forty eight dollars playing poker in tournaments last year the winnings were split evenly among the P place how much how much of money did each how much I guess you say how much money not how much of money is a grammatical error how much money did each player receive write your answer as an expression so they had five hundred and forty eight dollars and hit the split it evenly among the P place so they're going to split it so I'm just going to backs last year or I literally could have I could have just clicked on this as well five hundred forty eight divided by P I'm going to divide the amount of money we got amongst the number of players so that's how much money each player actually receives let's check the answer and got it right let's do a few more of these Phil received a prize of X dollars from a poker tournament the tournament cost him a hundred dollars to enter what were Phil's net winnings from the tournament write your answer as an expression or his net winnings okay he gets X dollars but it's not like he just walks away with X I mean he does get the X dollars but he had to pay something to enter the tournament he had to pay a hundred dollars to enter the tournament so for example if X was 105 dollars he wins 105 dollars but if he had to spend a hundred dollars to enter the tournament that his net would be a hundred five minus 100 or five dollars so this is giving us the net we're getting how much he got but we're subtracting how much he actually had to spend let's do one more of these Hilary made 48 chocolate chip cookies and why sugar cookies how many total cookies did Hilary make well 48 chocolate chip cookies and then to add that the number of sugar cookies she made and there you have it that's the total number of cookies she made it she made two sugar cookies this would why would be two and she would have made a total of 50 cookies if she made a hundred sugar cookies then this would be a hundred plus 48 which would be 148 total cookies so hopefully that gives you a little bit of practice and I encourage you to do this exercise so you get a lot more practice
