Checking whether fractions are equivalent

Transcript

Checking whether fractions are equivalentLet’s take an example Check whether 𝟏/𝟐, 𝟏𝟐𝟖/𝟐𝟓𝟔 are equivalent. To check, we make both fractions equal. 1/2 = 128/256 And then cross multiply 1/2 = 128/256 1 × 256 = 128 × 2 256 = 256 Since this is true 1/2, 128/256 are equivalent Check whether 𝟏/𝟑, 𝟗𝟗/𝟐𝟗𝟕 are equivalent. To check, we make both fractions equal. 1/3 = 99/297 And then cross multiply 1/3 = 99/297 1 × 297 = 99 × 3 297 = 297 Since this is true 1/2, 99/297 are equivalent Check whether 𝟒/𝟓, 𝟐𝟖/𝟑𝟓 are equivalent. To check, we make both fractions equal. 4/5 = 28/35 And then cross multiply 4/5 = 28/35 4 × 35 = 28 × 5 140 = 140 Since this is true. 4/5, 28/35 are equivalent.
