Cross-multiply. A/B = C/D if AD = BC
first you have to find the common denominator and make the 2 fractions denominators the same then you add them and divide them
Add them together and divide by 2.
Add them together, then divide by 2.
it helps you find the distance between fractions because the new name should be an equivalent fraction. Therefore it should be able to be divided\multiplied by 2 to make the original number.
Example- 2/4=4/8 all u have 2 do is x2 the numerater and denominator and ur sure 2 find ton and tons of = fractions
Denominator
2/5
Multiply them by 1/2 and you have half of the original fraction.
You multiply the fractions
All fractions are rational numbers because irrational numbers can't be expressed as fractions
To divide two fractions, invert the second one and multiply. 2/3 ÷ 3/4 = 2/3 x 4/3
take their averages to find a fraction between 1/4 and 1/3 take [(1/4) + (1/3)]/2 to get 7/24
