3 : 42 = 1 : 14
Solution:
R
educe the ratio (3:42) further with the greatest common factor (GCF).
The GCF of 3 and 42 is 3
To find the greatest common factor you need to use a number chart and see what number you can count by that has both of the same numbers that you need in it such as if you count by 3s = (3),6,9,12,15,18,21,24,27,30,33,36,39,(42)
You get both the numbers that your looking for. 3,42
Divide both terms (3,42) by the GCF, 3
3 ÷ 3 = 1
42 ÷ 3 = 14
YOU CAN CHECK YOUR ANSWER AND GET YOUR ANSWER BY:
You can multiply GCD 1,14 by term (3,42)
you can find out what to multiply by counting how many numbers it takes to get to your number:
(3), 6, 9, 12, 15, 18,21,24,27,30,33,36,39,(42)
(1) (3)
2 6
3 9
4 12
5 15
6 18
7 21
8 24
9 27
10 30
11 33
12 36
13 39
(14) (42) =
You want to multiply the number your counting by the number you land on that you have by counting by ones
3 * 1 = 3
3 * 14 = 42
ANSWER:
3 : 42 = 1 : 14
Hopefully this makes some sense hopefully you find a way to understand Ratios a little better now.
