I need help pleessse
wariber [46]

Answer:

1.  8/3

2.   1/7

3.  1/12

4.  1/27

Step-by-step explanation:

1.  3/8 * m = 1

Multiply by 8/3

8/3 * 3/8 m = 1* 8/3

m = 8/3


2.  7 * m = 1

Divide by 7

7*m /7 = 1/7

m = 1/7


3.  3 ÷m = 36

Multiply by m

3 ÷m * m = 36*m

3 = 36*m

Divide by 36

3/36 = 36*m/26

1/12 = m


4.  4/9 ÷m = 12

Multiply by m

4/9 ÷m * m = 12*m

4/9 = 12*m

Multiply by 1/12

4/9 *1/12 = 12*m * 1/12

4/12 *1/9 = m

1/3*1/9 =m

1/27
