lubasha [3.4K]

Answer:

He use 120 grams of flour.

Step-by-step explanation:

Given:

Flaky pastry can be made using flour and fat in the ratio 4 : 3. Jake makes some flaky pastry using 90 grams of fat.

Now, to find the weight of flour he use in making flaky pastry.

Let the weight of flour be x.

Weight of fat = 90 grams.

The ratio of flour and fat used in making flaky pastry is 4 : 3.

<em>As, 4 is equivalent to 3.</em>

<em>Thus, </em>x<em> is equivalent to 90.</em>

Now, to solve using cross multiplication method:

\frac{4}{3} =\frac{x}{90} \\\\By\ cross\ multiplying\ we\ get:\\\\360=3x\\\\Dividing\ both\ sides\ by\ 3\ we\ get:\\\\120=x\\\\x=120\ grams.

Therefore, he use 120 grams of flour.
