Here are a couple:
a2) 4/18= 2/9
b2) 1/3= 5/15
b2)1/3=5/15 how you did this please explain to me thank you.
multiply numerator and denominator by the same factor. In this case, 5. It could have been any other number.
To find an equivalent fraction using division, you can divide both the numerator and denominator of the given fraction by the same number. Here's how to find the equivalent fractions for the examples you provided:
(1) 15/20:
To simplify this fraction, you can divide both the numerator and denominator by their greatest common factor, which is 5. So, you divide 15 by 5 and 20 by 5, resulting in the equivalent fraction:
15 ÷ 5 = 3
20 ÷ 5 = 4
Therefore, the equivalent fraction of 15/20 is 3/4.
(2) 4/18:
To simplify this fraction, you can divide both the numerator and denominator by their greatest common factor, which is 2. So, you divide 4 by 2 and 18 by 2, resulting in the equivalent fraction:
4 ÷ 2 = 2
18 ÷ 2 = 9
Therefore, the equivalent fraction of 4/18 is 2/9.
To find an equivalent fraction using multiplication, you can multiply both the numerator and denominator of the given fraction by the same number. Here's how to find the equivalent fractions for the examples you provided:
(1) 3/8:
To find an equivalent fraction, you can multiply both the numerator and denominator by the same number. Let's choose 2 as the multiplier. Multiply 3 by 2, and multiply 8 by 2, resulting in the equivalent fraction:
3 × 2 = 6
8 × 2 = 16
Therefore, the equivalent fraction of 3/8 is 6/16.
(2) 1/3:
To find an equivalent fraction, you can multiply both the numerator and denominator by the same number. Let's choose 4 as the multiplier. Multiply 1 by 4, and multiply 3 by 4, resulting in the equivalent fraction:
1 × 4 = 4
3 × 4 = 12
Therefore, the equivalent fraction of 1/3 is 4/12.
