To solve this problem, we must multiply 1/12 by 4/5. We do this because we are trying to make 1/12 of the recipe, which calls for 4/5 cup of water. This means that we need to know what 1/12 of 4/5 is. We know that the word "of" in math refers to multiplication, so thus we need to find 1/12 * 4/5 by multiplying the two numerators and two denominators together.
1/12 * 4/5
(1*4)/(12*5)
4/60
To simplify this fraction, we need to divide both the numerator and denominator by the greatest common factor of the two numbers. This means the number that both the numerator and the denominator are divisible by (they divide evenly). The GCF of 4 and 60 is 4, so we divide by 4, as follows:
(4/4) / (60/4)
1/15
Therefore, your answer is that you need 1/15 cup of water to make the smaller portion of the recipe.
Hope this helps!
