Simplifying Fractions: Is 3/8 in its simplest form?
A fraction is considered simplified or reduced when the greatest common divisor (GCD) of the numerator and the denominator is 1. In the case of 3/8, the GCD of 3 and 8 is 1, meaning 3/8 is already in its simplest form. This is because 3 is a prime number and 8 (2 x 2 x 2) does not share any factors with 3 other than 1 Nothing fancy..
Frequently Asked Questions (FAQ)
Q: What is 3/8 as a decimal?
A: 3/8 is equal to 0.375 And it works..
Q: What is 3/8 as a percentage?
A: 3/8 is equal to 37.5%.
Q: How do I add 3/8 and 1/4?
A: First, find a common denominator (which is 8). 1/4 becomes 2/8. Then add the numerators: 3/8 + 2/8 = 5/8.
Q: How do I multiply 3/8 by 2/3?
A: Multiply the numerators (3 x 2 = 6) and the denominators (8 x 3 = 24). This gives 6/24, which simplifies to 1/4 Nothing fancy..
Q: How do I divide 3/8 by 1/2?
A: Invert the second fraction (1/2 becomes 2/1) and then multiply: (3/8) x (2/1) = 6/8, which simplifies to 3/4.
Q: Is 3/8 a proper or improper fraction?
