My recipe for one serving of fruit smoothie includes1 1/2 apples, 1/3 of a banana,1/5 of a mango and 5 raspberries. I want to make the smallest possible number of servings without having part of any fruit left over. How many raspberries do I need?

Respuesta :

Answer:

150

Step-by-step explanation:

One serving need:

[tex]\frac{3}{2}[/tex] apples, [tex]\frac{1}{3}[/tex] banana, [tex]\frac{1}{5}[/tex] mango, 5 raspberries

without having any fruit left over means:

all the fruit needed are integer

so we should find how many serves will cause the fruit needed are integer.

[tex]\frac{3}{2}=\frac{3\times3\times5}{2\times3\times5}=\frac{45}{30}[/tex]

[tex]\frac{1}{3}=\frac{1\times2\times5}{3\times2\times5}=\frac{10}{30}[/tex]

[tex]\frac{1}{5}=\frac{1\times3\times2}{5\times3\times2}=\frac{6}{30}[/tex]

⇒ 30 serving need fruit 45 apple, 10 banana, 6 mango, and the raspberries need:

[tex]5\times30=150[/tex]

I hope this helps you
