Equivalent Rational Numbers
Equivalent Rational Numbers
Equivalent Rational Number:
If a/b is a rational number and m is a non-zero integer then (a×m)/(b×m) is a rational number equivalent to a/b
.
For example, rational numbers 12/15
, 20/25, (−28)/(−35), (−48)/(−60) are equivalent to the rational number 4/5
.
We know that if we multiply the numerator and denominator of a fraction by the same positive integer, the value of the fraction does not change.
For example, the fractions 3/7
and 21/49 are equal because the numerator and the denominator of 21/49 can be obtained by multiplying each of the numerator and denominator of 3/7 by 7
Equivalent rational numbers by division:
If a/b is a rational number and m is a common divisor of a and b, then (a÷m)/(b÷m) is a rational number equivalent to a/b
.For example, rational numbers (−48)/(−60)
, (−28)/(−35), 20/25, 12/15 are equivalent to the rational number 4/5
We know that if we divide the numerator and denominator of a fraction by a common divisor, then the value of the fraction does not change.
For example, 48/64
= (48÷16)/(64÷16) = 34

Students / Parents Reviews [20]
When I have not joined Abhyas Academy, my skills of solving maths problems were not clear. But, after joining it, my skills have been developed and my concepts of science and SST are very well. I also came to know about other subjects such as vedic maths and reasoning.
