Question

frações equivalentes:
A)55/60
B)11/165
C)75/175
D)252/630
E)175/140
F)184/253

(POR FAVOR ME AJUDEM!!)​

Answer 1

a) mdc(55,60)=5

$\frac{55 \div 5}{60 \div 5} = \frac{11}{12}$

b) mdc(11,165)=11

$\frac{11 \div 11}{165 \div 11} = \frac{1}{15}$

c) mdc(75,175)=25

$\frac{75 \div 25}{175 \div 25} = \frac{3}{7}$

d) mdc(252,630)=126

$\frac{252 \div 126}{630 \div 126} = \frac{2}{5}$

e) mdc(175,140)=35

$\frac{175 \div 35}{140 \div 35} = \frac{5}{4}$

f) mdc(184,253)=23

$\frac{184 \div 23}{253 \div 23} = \frac{8}{11}$

Espero ter ajudado bons estudos :)
