Question

write 2\3 and 3\4 as a of actions with a common denominator

Answer 1

take lcm of denominators

3 and 4 dont have a common factor

so. take 3×4 as lcm

we can multiply two numbers when both dont have a common factor to do prime factorization for finding lcm

now multiply both numerator and denominator with a number which gives (12) i.e lcm

$2/3×4/4=8/12$

$3/4×3/3=9/12$

now we got 8/12 and 9/12 which have same denominators
