Question

There are about 1.5 grams of fat in 1 tablespoon of hummus. How many grams of fat are in 2.5 cups of hummus?

Answer 1

See a solution process below:

Explanation:

The conversion factor for tablespoons to cups is:

`1" cup" = 16" tbl"`

To find the number of tablespoons in 2.5 cups, multiply each side of the equation by `color(red)(2.5)` giving:

`color(red)(2.5) xx 1" cup" = color(red)(2.5) xx 16" tbl"`

`2.5" cup" = 40" tbl"`

In the problem we are told 1 tablespoon contains about 1.5 grams of fat, which we can write as:

`1" tbl" = 1.5"g"`

To find how much fat is in 40 tablespoons (which is the same as 2.5 cups) we multiply each side of the equation by `color(red)(40)` giving:

`color(red)(40) xx 1" tbl" = color(red)(40) xx 1.5"g"`

`40" tbl" = 60"g"`

Therefore, 2.5 cups of hummus contains 60 grams of fat.
