Question

 

1 phần 2 nhân 3 phần 4 cộng 1 phần 2 nhân 1 phần 4

 

Answer 1

1 phần 2

Answer 2

\(\frac{1}{2}\times\frac{3}{4}+\frac{1}{2}\times\frac{1}{4}\)

\(=\frac{1}{2}\times(\frac{3}{4}+\frac{1}{4})\)

\(=\frac{1}{2}\times1\)

\(=\frac{1}{2}\)

Chúc bạn học tốt

Answer 3

Trl:

\(\frac{1}{2}\times\frac{3}{4}+\frac{1}{2}\times\frac{1}{4}\)

\(=\frac{1}{2}\times\left(\frac{3}{4}+\frac{1}{4}\right)\)

\(=\frac{1}{2}\times1\)

\(=\frac{1}{2}\)

Answer 4

Kết quả là 1/2 .

Answer 5

1/2×(3/4+1/4)

1/2×1

1/2

Answer 6

\(\frac{1}{2}\)x\(\frac{3}{4}\)+\(\frac{1}{2}\)x\(\frac{1}{4}\)

=\(\frac{1}{2}\)x(\(\frac{3}{4}\)+\(\frac{1}{4}\))

=\(\frac{1}{2}\)x1

=\(\frac{1}{2}\)

Answer 7

Trả lời:

\(\frac{1}{2}\times\frac{3}{4}+\frac{1}{2}\times\frac{1}{4}\)

\(=\frac{1}{2}\times\left(\frac{3}{4}+\frac{1}{4}\right)\)

\(=\frac{1}{2}\times1\)

\(=\frac{1}{2}\)

Answer 8

1/2 * 3/4 + 1/2 * 1/4

=1/2 * [ 3/4 + 1/4 ]

=1/2 * 4/4 

=1/2 * 1

= 1/2.
