Finding equivalent fractionsLet’s take fraction
1/2
Equivalent fractions will be
1/2 × 2/2
1/2 × 3/3
1/2 × 4/4
1/2 × 5/5
1/2 × 100/100
Here, we are multiplying by 1
So, the fraction remains the same
Suppose we have to find an equivalent of 1/2 with denominator 512.
So,
1/2 = "⎕" /512
1/2 × 512 = "⎕"
"⎕" = 1/2 × 512
"⎕" = 256
∴ Equivalent fraction = 𝟐𝟓𝟔/𝟓𝟏𝟐
Find equivalent fraction of 𝟐/𝟑 with denominator & Numerator 6.
So,
2/3 = 6/"⎕"
Cross multiplying
2 × "⎕" = 6 × 3
"⎕" = (6 × 3)/2
"⎕" = 18/2
"⎕" = 9
∴ Equivalent fraction = 𝟔/𝟗
