3/5 + blank over 3 equals 14/15. whats the missing number

x = 1/3

Step-by-step explanation:

3/5 + x = 14/15

we need to get a common denominator 15

3/5 * 3/3 = 9/15

9/15 + x = 14/15

subtract 9/15 from each side

9/15 - 9/15 + x = 14/15 - 9/15

x = 5/15

this simplifies  divide the top and bottom by 5

x = 1/3

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!
