What is the simplest form of the ratio 40 : 16?

2 answers:

7 0

Well you can always start by dividing with the simplest number which is two.
Divide as many times as need
Last I checked it was divide 2 from 40, 3 times to get the answer of 5 and then divide 16 the same amount of times for the answer of 2

The answer would be I'm assuming 5 : 2
I said assuming I maybe wrong
Ask a teacher for help if I'm wrong.

I really need help plz

The answer is choice A.

In this problem, we are shrinking the poster by 1/4 of its size.

Which means you need to divide the sides by 4
For width:
$w = \frac{32}{4} = 8$
For length:
$l = \frac{28}{4} = 7$

The pyrotechnic team for Fist Bump’s tour want to know how high the arena is to 2 decimal places. The arena is 61.3786 metres hi

Aloiza [94]

When you find any value to x amount of decimal places, you need to go to the term AFTER that to determine the correct value. So, for this, take 61.378 metres. From here, look if the last number is 4 or less. If the number is 4 or less, take the leftmost number off, and you will have your answer (if we had 61.373, the correct answer would be 61.37). If the number is 5 or more, take the leftmost number off, and add 1 to the new leftmost number. Since the last number is 8, the correct answer here is 61.38 metres high. If adding 1 makes the number 10, keep the 0 at the end. So, if you had 61.399, you would make it 61.40

A bag contains 7 red marbles, 3 blue marbles and 5 green marbles. If three marbles

worty [1.4K]

Answer:

3.7%

Step-by-step explanation:

We know that from this situation, the probability of drawing a single green marble is 1/3. However, to find the probability of drawing 3 green marbles, we will need to do:

$P= \frac{1}{3}* \frac{1}{3}*\frac{1}{3}$

We get a probability of:

$P= \frac{1}{27}$

This converts to a percentage of:

$\frac{1}{27}= 0.037 \\ 0.037*100= 3.7%$

We get a percentage of 3.7%
