Answer 1

Answer:

Given fractions are 1/4,5/8,7/12 and 13/24

(Refer image)

LCM of 4,8,12,24=(2×2×2×3)=24

Converting each of the given fractions into an equivalent fraction with denominator as 30

We get

(1×6)/(4×6)=6/24

(5×3)/(8×3)=15/24

(7×2)/(12×2)=14/24

(13×1)/(24×1)=13/24

∴6/24,15/24,14/24, and 13/24 are the required like fractions.

solution

Step-by-step explanation:

Given fractions are 3/5,7/10,8/15 and 11/30

(Refer image)

LCM of 5,10,15,30=(5×3×2)=30

Converting each of the given fractions into an equivalent fraction with denominator as 30

We get

(3×6)/(5×6)=18/30

(7×3)/(10×3)=21/30

(8×2)/(15×2)=16/30

(11×1)/(30×1)=11/30

∴18/30,21/30,16/30 and 11/30 are the required like fractions.
