Write the ratio 12:16:8 in simplest form

Morgarella [4.7K]

Answer:

$\huge\boxed{\bf\: 3:4:2}$

Step-by-step explanation:

In the given ratio, $12:16:8$ , we can see that all the 3 numbers in ratio are multiples of 4. Hence the lowest common multiple (LCM) of the given ratio = 4.

Now, let's divide the 3 numbers by 4.

$12:16:8\\= \frac{12}{4}:\frac{16}{4}:\frac{8}{4}\\=\boxed{\bf\: 3:4:2}$

This ratio cannot be further simplified as they don't have any common multiples except for 1.

So, the simplified ratio = $\boxed{\bf\: 3:4:2}$

Tickets to a school basketball game cost $4 for students and $7 for adults. At the end of the night, 168 tickets are sold for a

stepan [7]

4s+7a=861
s+a=168

This can be solved using either elimination or substitution. I am going to use substitution.

Solve s+a=168 for s
s=168-a

Replace 168-a for s in 4s+7a=861
4(168-a)+7a=861
672-4a+7a=861

Solve for a
672+3a=861
3a=189
a=63

Substitute 63 for a in s=168-a
s=168-63=105

So, s=105 student tickets and a=63 adult tickets
