Answer 1

4

12

43/4

Answer 2

2+2=4

3+9=12

9+(3/4+1/4*4)=9+1,75=10,75

Answer 3

2+2=4

3+9=12

9+(3/4+1/4.4)=43/4

Answer 4

4

12

43/4

Answer 5

2+2=4

3+9=12

\(9+\left(\frac{3}{4}+\frac{1}{4}\times4\right)=9+\left(\frac{3}{4}+1\right)=9+\frac{7}{4}=\frac{43}{4}\)

=.= hok tốt!!

Answer 6

\(2+2=4\)

\(3+9=12\)

\(9+(\frac{3}{4}+\frac{1}{4}\times4)\)

\(=9+(\frac{3}{4}+\frac{4}{4})\)

\(=9+\frac{7}{4}\)

\(=\frac{43}{4}\)

Answer 7

2 + 2 = 4

3 + 9 = 12

\(9+\left(\frac{3}{4}+\frac{1}{4}x4\right)\)

\(9+\left(\frac{3}{4}+\frac{4}{4}\right)\)

\(9+\frac{7}{4}=\frac{43}{3}=10,75\)

Answer 8

\(2+2=4\)

\(3+9=12\)

\(9+\left(\frac{3}{4}+\frac{1}{4}\times4\right)=9+\left(\frac{3}{4}+1\right)=9+\frac{7}{4}=\frac{43}{4}=10,75\)

hok tốt~~

Answer 9

1)\(2+2=4\)

2)\(3+9=12\)

3)\(9+\left(\frac{3}{4}+\frac{1}{4}\times4\right)\)

\(=9+\left(\frac{4}{4}\times4\right)\)

\(=9+\left(1\times4\right)\)

\(=9+4\)

\(=13\)

Answer 10

3làm

2+2=4

3+9=12

\(9+\left(\frac{3}{4}+\frac{1}{4}x4\right)\)

\(=9+\left(\frac{3}{4}+1\right)\)

\(=9+\left(\frac{7}{4}\right)\)

\(=\frac{36}{4}+\frac{7}{4}\)\(=\frac{33}{4}\)

hk tốt

Answer 11

Trả lời :
