Rational Number Equivalent to 5/7
A rational number is any number that can be expressed as a ratio of two integers. Therefore, to find a rational number equivalent to 5/7, we need to express 5/7 as a fraction with integers in the numerator and denominator.
Finding the Equivalent Fraction
To find the equivalent fraction, we need to multiply both the numerator and denominator of 5/7 by the same integer. This integer should be chosen in such a way that the numerator and denominator become integers.
One way to do this is to multiply both the numerator and denominator of 5/7 by the denominator of the fraction, which is 7. This gives:
5/7 x 7/7 = 35/49
Therefore, the rational number equivalent to 5/7 is 35/49.
Verifying the Equivalent Fraction
We can verify that 35/49 is equivalent to 5/7 by simplifying the fraction. To simplify a fraction, we need to find the greatest common factor (GCF) of the numerator and denominator and divide both by it.
The GCF of 35 and 49 is 7. Dividing both the numerator and denominator by 7 gives:
35/49 ÷ 7/7 = 5/7
Therefore, 35/49 is equivalent to 5/7.
