Ineed to know what number 9 is i don’t understand it

The answer is (6/25). I just multiplied the 2 numbers, but I'll explain with something simpler:

Take the number 100, let's say I want (1/10) from that 100,

and from that (1/10), I want (4/5).

Well a tenth of 100 is 10, and four fifths of 10 is 8, thus we have 8/100 as a total (or 4/50)

The same answer can be found when multiplying (1/10) and (4/5), giving us (4/50) or (8/100)

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!
