Anna has a recipe for pumpkin bars. She uses 2 ½ cups of sugar for every 3 pans of pumpkin bars. AJ wants to follow the same rec

Kisachek [45]

Answer:

$2.5h = 3g$

Step-by-step explanation:

Given

$Sugar = 2\frac{1}{2}\ cups$

$Bars = 3\ pans$

Required

Determine the equation for h pans and g cups

We have that:

$Sugar = g$

$Bars = h$

To do this, we make use of the following equivalent ratios.

$Bars : Sugar = Bars : Sugar$

So, we have:

$3 : 2\frac{1}{2} = h : g$

Express fraction as decimal

$3 : 2.5 = h : g$

Express as fraction

$\frac{3}{2.5} = \frac{h}{g}$

Cross multiply

$2.5h = 3g$

No options were given. So, I will stop here
