Rút gọn rồi tính:

a) $\frac{16}{24}–\frac{1}{3}=\frac{2}{3}–\frac{1}{3}=\frac{2–1}{3}=\frac{1}{3}$     

b) $\frac{4}{5}–\frac{12}{60}=\frac{4}{5}–\frac{1}{5}=\frac{3}{5}$

Tính rồi rút gọn:

a) $\frac{17}{6}–\frac{2}{6}=\frac{17–2}{6}=\frac{15}{6}=\frac{5}{2}$             

b) $\frac{16}{15}–\frac{11}{15}=\frac{16–11}{15}=\frac{5}{15}=\frac{1}{3}$

c) $\frac{19}{12}–\frac{13}{12}=\frac{19–13}{12}=\frac{6}{12}=\frac{1}{2}$

=\(\frac{4+8+12+16}{2+10+15+20}\)

=\(\frac{40}{37}\)

bạn nào có lòng tốt giúp mình với nha huhu nhanh chóng giúp mình nha huhu

bn ơi bn viết lại thành số cụ thể đc ko mik khó đọc 

\(\frac{8}{15}+\frac{2}{3}=\frac{8}{15}+\frac{10}{15}=\frac{18}{15}=\frac{6}{5}\)

\(\frac{3}{7}+\frac{4}{8}=\frac{3}{7}+\frac{1}{2}=\frac{6}{14}+\frac{7}{14}=\frac{13}{14}\)

Nói trước là tui rút gọn luôn rồi nha

Câu thứ nhất = 6 phần 5

Câu thứ nhì = 13 phần 14

Đảm bảo đúng 100%

\(\frac{1}{4}+\frac{3}{5}=\frac{17}{20}\)

\(\frac{4}{5}+\frac{3}{2}=\frac{23}{10}\)

\(\frac{4}{5}+\frac{3}{15}=\frac{4}{5}+\frac{1}{5}=1\)

\(\frac{2}{3}+\frac{32}{24}=\frac{2}{3}+\frac{4}{3}=2\)

\(\frac{5}{6}+\frac{15}{18}=\frac{5}{6}+\frac{5}{6}=\frac{10}{6}=\frac{5}{3}\)

\(\frac{8}{15}+\frac{2}{3}=\frac{8}{15}+\frac{10}{15}=\frac{18}{15}=\frac{6}{5}\)

\(\frac{3}{7}+\frac{4}{8}=\frac{24}{56}+\frac{28}{56}=\frac{52}{56}=\frac{13}{14}\)

_HT_

Murad trả lời đúng rồi đó! 

a)=8/15 + 10/15 = 18/15 = 6/5

b)=24/56 + 28/56 = 52/56 = 13/14

a) 6 phan 5

b) 13 phan 14

= \(\frac{10}{18}\) = \(\frac{2}{5}\).

= \(\frac{7}{15}\) ( minh khong rut gon duoc vi no khong chia het co so nao ca )

\(a)\frac{3}{4}+\frac{1}{3}+\frac{2}{5}=\frac{45+20+24}{60}=\frac{89}{60}\)

\(b)\)Rút gọn rồi tính

\(a)\frac{3}{18}+\frac{4}{7}=\frac{1}{6}+\frac{4}{7}=\frac{7+24}{42}=\frac{31}{42}\)

\(b)\frac{12}{24}+\frac{12}{15}=\frac{1}{2}+\frac{4}{5}=\frac{5+8}{10}=\frac{13}{10}\)

\(\dfrac{3}{12}+\dfrac{1}{4}=\dfrac{3:3}{12:3}+\dfrac{1}{4}=\dfrac{1}{4}+\dfrac{1}{4}=\dfrac{2}{4}=\dfrac{1}{2}\)

\(\dfrac{4}{10}+\dfrac{3}{5}=\dfrac{4:2}{10:2}+\dfrac{3}{5}=\dfrac{2}{5}+\dfrac{3}{5}=\dfrac{5}{5}=1\)

\(\dfrac{12}{27}+\dfrac{2}{9}=\dfrac{12:3}{27:3}+\dfrac{2}{9}=\dfrac{4}{9}+\dfrac{2}{9}=\dfrac{6}{9}=\dfrac{2}{3}\)

\(\dfrac{7}{3}+\dfrac{20}{15}=\dfrac{7}{3}+\dfrac{20:5}{15:5}=\dfrac{7}{3}+\dfrac{4}{3}=\dfrac{11}{3}\)
