=26/100+9%+41%+24%
=26%+9%+41%+24%
=26%+24%+9%+41%=50%+50%=100%=1
26 % + 9 % + 41 % + 24 %
= ( 26 % + 24% ) + ( 41 % + 9 % )
=50 % + 50 %
=100 % =1
\(\frac{13}{50}+9\%+\frac{41}{100}+0,24\)
\(=\frac{13}{50}+\frac{9}{100}+\frac{41}{100}+\frac{24}{100}\)
\(=\frac{13}{50}+\left[\frac{9}{100}+\frac{41}{100}+\frac{24}{100}\right]\)
\(=\frac{13}{50}+\frac{74}{100}=\frac{13}{50}+\frac{37}{50}=1\)

=26%+9%+41%+24%
=(26%+24%)+(9%+41%)
=50%+50%
=100%
B=2/1.3 + 2/3.5 + 2/5.7 +...+ 2/299.301
B=1-1/3+1/3-1/5+1/5-1/7+...+1/299-1/301=1-1/301=300/301
\(Ta có: \frac{2}{3}=\frac{1}{1}-\frac{1}{3}\);
\(\frac{2}{15}=\frac{1}{3}-\frac{1}{5}\);
\(\frac{2}{35}=\frac{1}{5}-\frac{1}{7}\) ; ... ; \(\frac{2}{89999}=\frac{1}{299}-\frac{1}{301}\).
=> B= \(\frac{1}{1}-\frac{1}{3}+\frac{1}{3}-\frac{1}{5}+...+\frac{1}{299}-\frac{1}{301}\)
=> B=\(\frac{1}{1}-\frac{1}{301}\)
=> B=\(\frac{300}{301}\)
=26/100+9/100+41/100+24/100
=(26+24+9+41)/100
=100/100
=1
13/50 + 9% + 41/100 + 0,24
= 0,26 + 0,09 + 0,41 + 0,24
= (0,26 + 0,24) + (0,09 + 0,41)
= 0,5 + 0,5
= 1
Chúc bạn học tốt.
😁😁😁
=\(\frac{26}{100}\)+\(\frac{9}{100}\)+\(\frac{41}{100}\)+\(\frac{24}{100}\)=(\(\frac{26}{100}\)+\(\frac{24}{100}\)) + ( \(\frac{9}{100}\)+\(\frac{41}{100}\)) =\(\frac{50}{100}\)+\(\frac{50}{100}\)= 1
nho k cho minh nhe
13/50 + 9% + 41/100 + 0,14
= 13/50 + 9/100 + 41/100 + 14/100
= 26/100 + 9/100 + 4/100 + 14/100
= 53/100
Tk và kb hộ mk nha! thanks
13/50 + 9% + 41/100 + 0,24
\(=\frac{26}{100}+\frac{9}{100}+\frac{41}{100}+\frac{24}{100}\)
\(=\frac{26+9+41+24}{100}\)
\(=\frac{\left(26+24\right)+\left(9+41\right)}{100}\)
\(=\frac{50+50}{100}\)
\(=\frac{100}{100}\)
\(=1\)
OK CHÚC BẠN HỌC TỐT !!!
THANK YOU TRƯỚC NHÉ !
13/50 + 9% + 41/100 + 0,24
= 0, 26 + 0, 09 + 0, 41 + 0, 24
= (0, 26 + 0, 24) + ( 0, 09 + 0, 41)
=0, 5 +0, 5
= 1
\(\frac{13}{50}+9\%+\frac{41}{100}+0,24\)
\(=\frac{26}{100}+\frac{9}{100}+\frac{41}{100}+\frac{24}{100}\)
\(=\frac{26+9+41+24}{100}\)
\(=1\)
Đơn giản hóa bài toán :
\(\frac{13}{50}+9\%+\frac{41}{100}+0,24\)
\(=\frac{26}{100}+\frac{9}{100}+\frac{41}{100}+\frac{24}{100}\)
\(=\frac{26+9+41+24}{100}\)
\(=\frac{100}{100}\)
A = \(\dfrac{13}{50}\) + 9% + 41/100 + 0,24
A = 0,26 + 0,09 + 0,41 + 0,24
A = (0,26 + 0,24) + ( 0,09 + 0,41)
A = 0,5 + 0,5
A = 1
Ta có : 13 50 + 9 100 + 41 100 + 6 25 9 100 + 41 100 ( ) + ( 13 50 + 6 25 ) 1 = 1 2 + 50 13+ 12 = 1 2 + 1 2 = 1
\(\frac{13}{50}+9\%+\frac{41}{10}+0,24\)
\(=\frac{13}{50}+\frac{9}{100}+\frac{41}{100}+\frac{24}{100}\)
\(=\frac{13}{50}+\left(\frac{9}{100}+\frac{41}{100}+\frac{24}{100}\right)\)
\(=\frac{13}{50}+\frac{74}{100}\)
\(=\frac{13}{50}+\frac{37}{50}=\frac{50}{50}=1\)
