PLEASE NO FAKES! i really need help i didnt do this math in a minute smh.

15

Step-by-step explanation:

To solve this we need to multiply from left to right:

another way to write 40 is 40/1

so multiply 3/8 and 40/1

(You need to multiply the top with the top and bottom with bottom)

3 times 40 is 120 8 times 1 is 8 so the answer will look like this:

120/8

But we can simplify it:

120 divided by 8 is 15

(If you don't know how to divide long division divide with smaller numbers like 2, 3, 5, 7, and so on)

Alternate way:

Divide by a prime number that can be divided in this case it is 2, stop when that number cannot be divided by that prime number

120: 120/2= 60    60/2= 30     30/2= 15

8: 8/2= 4    4/2= 2     2/2= 1

Hope this helps!
