According 6381

According to the recipe, 0.8 kg of rice, 0.65 kg of meat, 300 g of carrots, 60 g of peas, 50 g of fat, and 10 g of salt are used to prepare 10 portions of dietary risotto. What weight of these types of food will need to be used to prepare 15 servings of risotto?

Correct answer:

a =  1.2 kg
b =  0.975 kg
c =  450 g
d =  90 g
e =  75 g
f =  15 g

Step-by-step explanation:

$$\begin{gathered} k=\frac{15}{10}=\frac{3}{2}=1.5 \\ a=0.8\cdot k=0.8\cdot \frac{3}{2}=\frac{6}{5}\text{kg}=1.2\text{kg} \end{gathered}$$

$b=0.65\cdot k=0.65\cdot \frac{3}{2}=\frac{39}{40}\text{kg}=0.975\text{kg}$

$c=300\cdot k=300\cdot \frac{3}{2}=\frac{300\cdot 3}{2}=\frac{900}{2}=450\text{g}$

$d=60\cdot k=60\cdot \frac{3}{2}=\frac{60\cdot 3}{2}=\frac{180}{2}=90\text{g}$

$e=50\cdot k=50\cdot \frac{3}{2}=\frac{50\cdot 3}{2}=\frac{150}{2}=75\text{g}$

$f=10\cdot k=10\cdot \frac{3}{2}=\frac{10\cdot 3}{2}=\frac{30}{2}=15\text{g}$
