Answer:
How to find equivalent fractions?
Two fractions are equivalent when they are both equal when written in the lowest terms. The fraction 18/
20 is equal to 9/
10 when reduced to the lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (9/
10
) by the same integer number, i.e., multiply by 2, 3, 4, 5, 6 ...
18/
20 is equivalent to 9/
10 because 9 x 2 = 18 and 10 x 2 = 20
27/
30 is equivalent to 9/
10 because 9 x 3 = 27 and 10 x 3 = 30
36/
40 is equivalent to 9/
10 because 9 x 4 = 36 and 10 x 4 = 40
and so on ...
At a glance, equivalent fractions look different, but if you reduce then to the lowest terms you will get the same value showing that they are equivalent. If a given fraction is not reduced to lowest terms, you can find other equivalent fractions by dividing both numerator and denominator by the same number.
What is an equivalent fraction? How to know if two fractions are equivalent?
Finding equivalent fractions can be ease if you use this rule:
Equivalent fractions definition: two fractions a/
b and c/
d 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 (a/
b and c/
d
) the equality will remain, i.e, a.d = b.c. So, here are some examples:
18
/20 is equivalent to 9
/10 because 18 x 10 = 20 x 9 = 180
27/
30 is equivalent to 9/
10 because 27 x 10 = 30 x 9 = 270
36/
40 is equivalent to 9/
10 because 36 x 10 = 40 x 9 = 360
