Please Solve this. Last Question of the Day So Points Increase a little bit. :)

5 cookies left

Step-by-step explanation:

First you make the fraction equal by multiplying them

2/3 multiply both numerator and denominator by 4

= 8/12

Now you divide 60 by 12 to find the amount to make the denominator 60

60 divided by 12 = 5

8/12 multiply both numerator and denominator by 5

= 40/60

So now we know the amounts

She gave 40 away so she has 20 left (60 - 40 = 20)

Now make 3/4 numerator and denominator by equal to 20

Multiply them by 5

15/20

She had 5 cookies left

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!
