Subtract -5/12-3/10 pl thx

-43/60

To find this answer, you must first make the denominators of each fraction the same. To do so, multiply -5/12 by 5/5 to get -25/60 and multiply 3/10 by 6/6 to get 18/60. Finally, you subtract the fraction. Keep in mind, the denominators stay the same (60) while the numerators are subtracted. -25 - 18 is -43. Thus making the answer -43/60.

I hope this helps!

answer: i don't understand. what are the options

step-by-step explanation:

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!
