Question

Tìm x: X: 4/5- 1/16=3/4 ( có thể chỉ trả lời đáp án ), đến cuối nếu chưa tối giải nhớ rút gọn

Answer 1

\(x:\dfrac{4}{5}-\dfrac{1}{16}=\dfrac{3}{4}\)

\(x:\dfrac{4}{5}=\dfrac{3}{4}+\dfrac{1}{16}\)

\(x:\dfrac{4}{5}=\dfrac{12}{16}+\dfrac{1}{16}\)

\(x:\dfrac{4}{5}=\dfrac{13}{16}\)

\(x=\dfrac{13}{16}\times\dfrac{4}{5}\)

\(x=\dfrac{13}{20}\)

Answer 2

x: 4/5= 3/4+1/16

x: 4/5= 13/16

x = 13/16 x 4/5

x = 13/20

Answer 3

X :\(\dfrac{4}{5}-\dfrac{1}{16}=\dfrac{3}{4}\)

=> \(x:\dfrac{4}{5}=\dfrac{3}{4}+\dfrac{1}{16}\)

=> \(x:\dfrac{4}{5}=\dfrac{13}{16}\)

=>       \(x=\dfrac{13}{16}\)x\(\dfrac{4}{5}\)

=>       \(x=\dfrac{13}{20}\)
