How do you find equivalent fractions?
Two fractions are equivalent when they are both equal when written in lowest terms. The fraction 42100 is equal to 2150 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (2150) by the same natural number, ie, multiply by 2, 3, 4, 5, 6 ...
- 42100 is equivalent to 2150 because 21 × 250 × 2 = 42100
- 63150 is equivalent to 2150 because 21 × 350 × 3 = 63150
- 84200 is equivalent to 2150 because 21 × 450 × 4 = 84200
- 105250 is equivalent to 2150 because 21 × 550 × 5 = 105250
- 126300 is equivalent to 2150 because 21 × 650 × 6 = 126300
- and so on ...
At a glance, equivalent fractions look different, but if you reduce them to the lowest terms, you will get the same value, showing that they are equivalent. If a given fraction is not reduced to the lowest terms, you can find other equivalent fractions by dividing both numerator and denominator by the same number.
What is an equivalent fraction? How do we know if two fractions are equivalent?
Finding equivalent fractions can be easy if you use this rule:
Equivalent fractions definition: two fractions ab and cd are equivalent only if the product (multiplication) of the numerator (a) of the first fraction and the denominator (d) of the other fraction is equal to the product of the denominator (b) of the first fraction and the numerator (c) of the other fraction.
In other words, if you cross-multiply (ab and cd), the equality will remain, i.e., a.d = b.c. So here are some examples:
- 42100 is equivalent to 2150 because 42 × 50 = 100 × 21 = 2100
- 63150 is equivalent to 2150 because 63 × 50 = 150 × 21 = 3150
- 84200 is equivalent to 2150 because 84 × 50 = 200 × 21 = 4200
