Answer:
[tex]\frac{1}{7}=\frac{5}{35}=\frac{3}{21}[/tex]
1/7 : b and d
[tex]\frac{3}{5}= \frac{12}{20}= \frac{21}{35}[/tex]
3/5 : c and e
Step-by-step explanation:
If you divide the numerator and denominator of [tex]\frac{5}{35}[/tex] by 5 you get 1/7
for 3/21 divide both numbers by 3, you get 1/7
The two statements above show why 1/7 is equal to b and d
for 12/20 divide both numbers by 5, you get 3/5 so 3/5 = 12/20
for 21/35 divide both numbers by 7, you get 3/5 so 3/5 = 21/30
the 2 statements above show why 3/5 is equal to c and e
as for a, 13/21, 13 is a prime number so and it isn't equal to 3/5 or 1/7
hope this helps!
