Question

arrange in ascending order 3/10 , 4/11 , 5/13

Answer 1

LCM of 10,11,13 = 1430

3×143/10×143=429/1430

4×130/11×130=520/1430

5×110/13×110=550/1430

thus, 429/1430<520/1430<550/1430

therefore, 3/10<4/11<5/13

Answer 2

Answer:

5 by 13

l.c.m of 10&11&13 is 1430

then divide all the denominators by 1430 respectively

and multiply the numerators with same nos. obtained by denominator

• firstly write smallest no. in numerator by denominator
• write second smallest no. by denominator
• then greatest no. by denominator

L.C.M. of 10/11/13 = 1430

3×143/10×143= 429 / 1430

4×130/11×130=520/1430

5×110/13×110= 550/1430

• 429/1430
• 520/1430
• 550/1430

• Ans= 3/10
• 4/11
• 5/13
