Answer:
<em>4/15 cups</em>
<em></em>
Step-by-step explanation:
If a cups scientist needs 12 cup baking soda for 45 liter of water, this can be expressed as;
12 cup of soda = 45 litres of water
To get the amount of soda needed for one litre, we will say;
x soda = 1 litre
Divide both equations;
12/x = 45/1
Cross multiply'45x = 12
x = 12/45
x = 4/15
<em>Hence the required answer us 4/15 cups</em>
<em></em>
The first step to this is to subtract 7 from both sides. The +7 and -7 cancel each other out leaving you with 3x=6 then divide by 3 on each side giving you x=2.
