Answer:

1:5 4:20

Step-by-step explanation:

Because say you got 1 right out of 5 on test you get a 20%

since 20 can go into a 100 5 times if whatever number is the 1rst time it can go into 5 it is a 20 like 4:20 because 4,8,12,16,20 see that's 5 numbers and 4 is the first.

In then 1:5 is another example it can go 5 times or one more is like 10:50=20% or 15:75.

Hope this helps have a great afternoon:)

Find [-4/5]×3/7×15/16×[-14/9]

dangina [55]

The given expression is $\frac{-4}{5} \times \frac{3}{7} \times \frac{15}{16} \times (\frac{-14}{9})$ .

We need to simplify the given expression.

<h3>What is a rational number?</h3>

In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.

Now group the rational numbers $(\frac{-4}{5}\times \frac{15}{16} ) \times (\frac{3}{7}\times (\frac{-14}{9}))$

$=(\frac{-4}{16}\times \frac{15}{5} ) \times (\frac{3}{9}\times (\frac{-14}{7}))$

$=(\frac{-1}{4}\times \frac{3}{1} ) \times (\frac{1}{3}\times (\frac{-2}{1}))$

$=(\frac{-3}{4} ) \times (\frac{-2}{3})=\frac{1}{2}$

Therefore, the simplified value of the given expression is $\frac{1}{2}$ .

The total number of muffins is 35 muffins

P(vanilla) = number of vanilla/ total

= 7/35

= 1/5

This is not likely to occur so it is an unlikely event
