75% I think.
because if you do 560 - 420 you get 140.
140 / 560 x 100 = 25
which means there is a 25% decrease, so they took 75%.
Answer:
75.5 cm
Step-by-step explanation:
S = (a+b)*h/2
h = 2 * S / (a+b) = 2 * 7701 / 204 = 75.5 cm
When creating a right triangle using three squares, the sides of the two squares with the smallest areas will create the right angle in the triangle (see image attached below).
<h3>Creating a Right Triangle with Three Squares</h3>
The right angle of a right triangle is formed by the two small legs of the right triangle that are perpendicular to each other.
Just like in the diagram attached below, the two squares with the smallest sides will form the right angle in the right triangle.
Therefore, we can conclude that when creating a right triangle using three squares, the sides of the two squares with the smallest areas will create the right angle in the triangle.

She need 1/12 cup of oil. A fraction is a portion of a whole or, more broadly, any number of equal parts. In everyday English, a fraction describes the number of parts of a specific size, such as one-half, eight-fifths, or three-quarters.
<h3>What is meant by fraction?</h3>

- fraction, A number expressed as a quotient in arithmetic, in which a numerator is divided by a denominator. Both are integers in a simple fraction.
- A complex fraction contains a fraction in either the numerator or the denominator. A proper fraction has a numerator that is less than the denominator. A fraction is a portion of a whole number and a method of dividing a number into equal parts.
<h3>How to find how much cup she want?</h3>
- She needs 1/3 cup of oil
- She have 1/4 cup of oil
To find how much need to obtain 1/3 of cup
we need to subtract what we have from what we need.
so , we have 1/4 and need 1/3
= 1/3 - 1/4
= 
= 1/12
she need 1/12 cup of oil more to make cake.
