Question

There is 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

Hint:You need a conversional relation between tablespoon and cups to solve this question which is given as one cup equals sixteen tablespoon. Now first calculate the number of tablespoons equivalent to 2.5 cups, then multiply that number with the given mass of fat in one tablespoon, you will get the required mass of fat.

Complete step by step solution:
In order to find how many grams of fat are in 2.5 cups of hummus, if it is given that there are about 1.5 grams of fat in 1 tablespoon of hummus. First, we have to know about the relation between tablespoon and cup,
According to international standards, 16 tablespoon is equivalent to one cup.
That means,
${\text{1}}\;{\text{cup}} = {\text{16}}\;{\text{tbl}}$
Here tbl stands for tablespoons
Multiplying $2.5$ both sides, we will get
$
{\text{2}}{\text{.5}} \times {\text{1}}\;{\text{cup}} = {\text{2}}{\text{.5}} \times
{\text{16}}\;{\text{tbl}} \\
{\text{2}}{\text{.5}}\;{\text{cup}} = 40\;{\text{tbl}} \\
$
Since one tablespoon of hummus have two and a half gram of fat, that means
${\text{1}}\;{\text{tbl}} = {\text{1}}{\text{.5}}\;{\text{gm}}$
Multiplying $40$ both sides, we will get
$
40 \times 1\;{\text{tbl}} = 40 \times 1.5\;{\text{gm}} \\
40\;{\text{tbl}} = 60\;{\text{gm}} \\
\therefore {\text{2}}{\text{.5}}\;{\text{cup}} = 40\;{\text{tbl}} = 60\;{\text{gm}} \\
$
Therefore there are about 60 gm (sixty grams) of fat available in 2.5 cups or 40 tablespoons.

Note: We have written at last that there are about… it is so because in the question too, data is given in an approximation it is not sure written. It is written too in the question that there are about 1.5 gm that is why we too have written it so and you should also follow this rule in other questions as well.
