# Butter fat

A quarter of kg butter contains 82% fat. How many grams of fat are in four cubes of butter?

Result

t =  820 g

#### Solution:

$n = 4 \ \\ \ \\ m = n \cdot \ \dfrac{ 1 }{ 4 } = 4 \cdot \ \dfrac{ 1 }{ 4 } = 1 \ kg \ \\ \ \\ q = 82 \% = \dfrac{ 82 }{ 100 } = 0.82 \ \\ \ \\ t_{ 1 } = q \cdot \ m = 0.82 \cdot \ 1 = \dfrac{ 41 }{ 50 } = 0.82 \ \\ \ \\ t = t_{ 1 } \rightarrow g = t_{ 1 } \cdot \ 1000 \ g = 820 \ g = 820 \ \text { g }$
