Question

Arrange the following ratios in ascending order:-
3:5, 7:20 and 8:15

Answer 1

Answer:

$\frac{7}{20} <\frac{8}{15} <\frac{3}{5}$

Step-by-step explanation:

$LCM = 60$

$\frac{3}{5} = \frac{3*12}{5*12} = \frac{36}{60}\\\\\\\frac{7}{20} = \frac{7*3}{20*3} = \frac{21}{60}\\\\\frac{8}{15} = \frac{8*4}{15*4} = \frac{32}{60}$

$\frac{21}{60} <\frac{32}{60} <\frac{36}{60} \\\\\frac{7}{20} <\frac{8}{15} <\frac{3}{5}$

Answer 2

Step-by-step explanation:

3×12/5×12=36/60

7×3/20×3=21/60

8×4/15×4=32/60

21/60<32/60<36/60
