Answer:
Han bebido la misma cantidad.
Step-by-step explanation:
De la pregunta,
Frederico = 2/5 vaso de leche
María = 4/10 vaso de leche
Simplificando el gozo de la leche para María
= 2/5
Por tanto, podemos decir que:
Sí, han bebido la misma cantidad.
Each term is being divided by -3, so the next three terms would be:
-1/3, 1/9, -1/27
X=length
y=width
Area (rectangle)=length x width
we suggest this system of equations:
y=x/5
xy=9/20
solve this system of equations by substitution method:
x(x/5)=9/20
x²/5=9/20
Least common multiple=20
4x²=9
x²=9/4
x=⁺₋√(9/4)
we have two solutions:
x₁=-3/2 it does not validate
x₂=3/2 ⇒y=x/5=(3/2)/5=3/10
The dimensions of the lake are:
lengh=3/2 miles
width=3/10 miles
to check:
Area=3/2 miles x 3/10 miles=9/20 miles².
width is 1/5 the length of the lake ⇒ 3/10 miles=(3/2) /5 miles
Ratios can be written as fractions
24:28 = 24/28...this can reduce to 6/7....as a ratio 6:7
if that is not an answer choice, then any fraction that is equivalent to 24/28, written as a ratio will be ur answer
