Problems on LCM & HCF Mcqs


Q.  Which of the following fractions is the largest?

a. 7/8
b. 13/16
c. 31/40
d. 63/80


ANSWER: See Answer
 
L.C.M of 8, 16, 40 and 80 = 80.

7/8 = 70/80; 13/16 = 65/80; 31/40 = 62/80
Since, 70/80 > 63/80 > 65/80 > 62/80,
So, 7/8 > 63/80 > 13/16 > 31/40
So, 7/8 is the largest.
