Question

Answer 1

` 7/8 + 1 : 3/7`

` = 7/8 + 1 xx 7/3`

` = 7/8 + 7/3`

` = 21/24 + 56/24`

` = 77/24`

Answer 2

\(\dfrac{7}{8}+1:\dfrac{3}{7}\\ =\dfrac{7}{8}+1\times\dfrac{7}{3}\\ =\dfrac{21}{24}+\dfrac{56}{24}\\ =\dfrac{77}{24}\)

Answer 3

\(\dfrac{7}{8}+1:\dfrac{3}{7}=\dfrac{7}{8}+1\times\dfrac{7}{3}=\dfrac{7}{8}+\dfrac{7}{3}=\dfrac{21}{24}+\dfrac{56}{24}=\dfrac{77}{24}\)

Answer 4

`7/8+1:3/7`

`=7/8+7/3`

`=77/24`

Answer 5

\(\dfrac{7}{8}+1:\dfrac{3}{7}=\dfrac{7}{8}+1\times\dfrac{7}{3}=\dfrac{7}{8}+\dfrac{7}{3}=\dfrac{77}{24}\)

Answer 6

Bài 4:

\(\dfrac{7}{8}+1:\dfrac{3}{7}=\dfrac{7}{8}+1\times\dfrac{7}{3}=\dfrac{7}{8}+\left(1\times\dfrac{7}{3}\right)=\dfrac{7}{8}+\dfrac{7}{3}=\dfrac{7\times3}{8\times3}+\dfrac{7\times8}{3\times8}=\dfrac{21}{24}+\dfrac{56}{24}=\dfrac{21+56}{24}=\dfrac{77}{24}.\)
