\(\frac{13}{50}+90\%+\frac{41}{100}+24\%\)
= \(\frac{26}{100}+\frac{90}{100}+\frac{41}{100}+\frac{24}{100}\)
= \(\left(\frac{26}{100}+\frac{24}{100}\right)+\frac{90}{100}+\frac{41}{100}\)
= \(\frac{50}{100}+\frac{90}{100}+\frac{41}{100}\)
= \(\frac{181}{100}\)
\(\frac{13}{50}+9\%+\frac{41}{100}+\frac{24}{100}\)
\(=\frac{26}{100}+\frac{9}{100}+\frac{41}{100}+\frac{24}{100}\)
\(=\frac{26+9+41+24}{100}=\frac{100}{100}=1\)
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%
=26%+9%+41%+24%
=100%=1
13/50+9%+41/100+0,24
= 25/100+9/100+41/100+24/100
= 25+9+41+24/100
= 99/100
Nhớ tích cho mình nhé !
\(\dfrac{13}{50}+9\%+\dfrac{41}{100}+0,24\)
\(=\dfrac{26}{100}+\dfrac{9}{100}+\dfrac{41}{100}+\dfrac{24}{100}\)
\(=\dfrac{26+9+41+24}{100}=1\)
=0.26+0.9+0.41+24=1.16+0.41+24=1.57+24=25.57
