Question

What is the ratio of 3:42?

Answer 1

1:14

Explanation:

3:42 => 3/42

3/42 to the lowest term is 1/14

Which is 1:14

Answer 2

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.
