b)13/50+9%+41/100+24%
c)678x874+251/678x874-623
Trả lời
a)4/5.9/7-4/5.3/14
=4/5(9/7-3/14)
=4/5(18/14-3/14)
=4/5.15/14
=6/7
b)13/50+9%+41/100+24%
=13/50+9/100+41/100+24/100
=26+9+41+24/100
=(26+24)+(9+41)/100
=100/100
=1
\(\frac{4}{5}\cdot\frac{9}{7}-\frac{4}{5}\cdot\frac{3}{14}\)
=\(\frac{4}{5}\cdot(\frac{9}{7}-\frac{3}{14})\)
=\(\frac{4}{5}\cdot\frac{15}{14}\)
=\(\frac{6}{7}\)
b,\(\frac{13}{50}\)+9%+\(\frac{41}{100}\)+24%
