LCD(49, 21) = 147
You need at least two fractions to find something in common.
2/3 and 3/4Looks like 12 here, so use form of one to convert both fractions to LCD form.4*2/4*3 and 3*3/3*48/12 and 9/12==========
Their product. If that's 1/6 and 1/5, the LCD is 30
The LCD is 60. (60/4 = 15, 60/5 = 12, 60/6 = 10)
