The three equivalent ratios are 27/6, 45/10, and 36/8.
Given,
The ratio of right-handed students to left-handed students is 18:4.
We need to find three equivalentratios of 18:4.
A ratio is denoted by A:B.
If the ratios are equal we called it proportion.
Example:
2/4 = 16/32 = 6/12
2/4 = 1/2
16/32 = 2/4 = 1/2
6/12 = 1/2
2/4, 16/32, and 6/12 are equivalent ratios and they are in proportion.
We have,
18:4
It can be written as:
= 18/4
Reducing it to the smallest term.
= 2 x 9 / 2 x 2
= 9 / 2
So,
We can have,
27/6, 45/10, and 36/8 as our equivalentratios.
27/6 = 3 x 9 / 3 x 2 = 9/2
45/10 = 5 x 9 / 5 x 2 = 9/2
36/8 = 4 x 9 / 4 x 2 = 9/2
Thus the three equivalent ratios are 27/6, 45/10, and 36/8.

Answer:
Step-by-step explanation:
First, do what is inside the parentheses (PEMDAS)
29+18= 47
Now do the other parentheses
17-8=9
now add them together cuz they r inside a bigger parentheses
9+47=56
now divide by 8
56/8=7
Answer:
Your answer is D. 16 3/4
Step-by-step explanation:
10 1/12 + 6 2/3 = 67
4
= 16 3/4
= 16.75
Calculation steps
Conversion a mixed number to a improper fraction: 10 1/12 = 10 · 12 + 1/12
= 121/12
Conversion a mixed number to a improper fraction:
6 2/3 = 6 · 3+2/3
= 20/3
Add: 121/12 + 20/3 = 121/12 + 20 · 4/3 · 4 = 121/12 + 80 12 = 121 + 80/12 = 201/12 = 67/4

Answer:
(2 2/9, 12 5/9)
Step-by-step explanation:
multiply both sides of x+2y=14 by 2: 2x+4y=28
Add 7x-4y=-8 and 2x+4y=28: 9x=20
x=20/9
Plug in 20/9 into x+2y=14: 20/9+2y=14
2y=11 7/9
y= 11 14/9
y= 12 5/9
