Answer 2

Answer:

7000 : 3

Step-by-step explanation:

Firstly, you will have to take note on the unit.

As you can see, the units aren't the same. One is in grams while the other is in milligrams.

The first step you have to do before you do anything is to change the unit.

Lets change the grams.

For 42 grams into milligrams, you will have to multiply 42 with 1000.

That would make 42000 milligrams.

Now you have the same unit, you can proceed on doing the ratio!

42000 mg : 18mg

As you can see, both number can be divisible by 3.

Which makes : 42000 ÷ 6 = 7000 , 18 ÷ 6 = 3

Therefore, the ratio will be 7000 : 3
