Answer:
x = 30
Step-by-step explanation:
10% fat = 0.1x
x = the solution, what we want to find
120 grams of 20% fat = 0.2 * 120
What we want is mixture of 18%
So....
0.1x + 0.2 * 120 = 0.18 (x + 120)
Solve:
0.1x + 24 = 0.18 (x +120)
0.1x + 24 = 0.18x + 21.6
24 = 0.08x + 21.6
x = 30

Answer:
Step-by-step explanation:
Divide: 1
3 : 14 = 13 · 4 1 = 1 · 4 3 · 1 = 43
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1
4 is 4 1
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - one third divided by one quarter = four thirds.
