Answer:
7.5
Step-by-step explanation:
step 1- how many times does 30 go into 4? The closest number divisible to 30 that is a factor of 4 is 28, which is 4 times 7. The first number you will write is 7.
Step 2- subtract 30 by 28, that should give you 2. Next, add a 0 next to it, which gives you 20, and if you remember right, 5 times 4 gives you 20, so the next number you will write is 5, and since you added a zero from literally nowhere you will add a decimal point to the right of 7, so the answer is 7.5 :)
