Carmen ran 5 1/2 miles on the track each lap around the track is 1/4 mile. how many laps did carman run

Carman run 22 laps

(5 1/2) / (1/4)    convert 5 1/2 to an improper fraction

(11/2) /(1/4)     when you divide the second number you flipped and multiply

11/2 * 4/1

22

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
