What is 2/5m=17/4 please help me bc I’m confused

lesantik [10]

Step-by-step explanation:

To find m, we need to divide 2/5 from both sides of the equation given.

Divide:

$\frac{2/5}{2/5} x=\frac{17/4}{2/5}$

Solving Dividing:

2/5 cancels out.

$\frac{17}{4} \div \frac{2}{5} =\frac{17}{4} \times\frac{5}{2} =85/8$

Equation:

$x=\frac{85}{8}$

$x =10.625, or: 10\frac{5}{8}$
