De ahí que la fracción de la mantequilla total que corresponde a cada postre sea 1/4
Si con 16 barras de mantequilla se prepararon 20 postres, esto se puede expresar como:
16 pegatinas = 20 postres
Para obtener la fracción del total de mantequilla que corresponde a cada postre, podemos escribir;
x = 1 postre
Divide ambas expresiones
16 / x = 20/1
20 veces = 16 * 1
20x = 16
x = 16/20
x = 4/5
De ahí que la fracción de la mantequilla total que corresponde a cada postre sea 1/4

Answer:
27.5cm^2
Step-by-step explanation:
you can cut the triangle to make two right triangles
so 11 is the height and the width is 2.5 since your cutting the triangle in half
so 11x2.5=27.5 since its a right triangle you have to divide by two 27.5/2=13.75
that's the answer for one of the triangles now multiply it by two since you need the two right triangle to make the other triangle so the answer is 27.5

Answer:
<em>The perimeter of the green cross is 32 cm</em>
Step-by-step explanation:
<u>Perimeter</u>
It's the sum of all the external side lengths of a given shape.
The green cross formed by two rectangles is shown in the figure below.
We have outlined the dimensions of the external sides of the resulting cross.
Note there are four corners of 2 cm by 2 cm and four sides of 4 cm each.
The total perimeter is:
8 * 2 cm + 4 * 4 cm = 16 cm + 16 cm = 32 cm
The perimeter of the green cross is 32 cm
