3 Ramón makes nectar for a hummingbird feeder by mixing 8 cups of water with 2 cups of sugar. Tiffany makes nectar by mixing 9 c

Butoxors [25]

Answer:

Tiffany's nectar is more sugary

Step-by-step explanation:

Given

Ramon:

$Water = 8\ cups$

$Sugar = 2\ cups$

Tiffany

$Water = 9\ cups$

$Sugar = 3\ cups$

Required

The nectar with more sugar

To do this, we simply calculate the fraction of sugar in both nectar.

This is calculated as:

$Fraction = \frac{Sugar}{Sugar + Water}$

For Ramon:

$Fraction = \frac{2}{8 + 2}$

$Fraction = \frac{2}{10} = 0.20$

For Tiffany

$Fraction = \frac{3}{3 + 9}$

$Fraction = \frac{3}{12} = 0.25$

From the calculations above:

$0.25 > 0.20$

Hence: Tiffany's nectar is more sugary
