Question

Explain how you can find the missing number in 3 4/5 divide [ ] = 2 5/7 then find the missing number. I need help now please.

Answer 1

find the missing number in 3 4/5 divide [ ] = 2 5/7

Let the unknown number be x

$\frac{3 \frac{4}{5}}{x}=2\frac{5}{7}$

$3\frac{4}{5}$ can be written as $\frac{19}{5}$

$2\frac{5}{7}$ can be written as $\frac{19}{7}$

So equation becomes

$\frac{\frac{19}{5}}{x}=\frac{19}{7}$

We need to get x alone, so we multiply by x on both sides

$\frac{19}{5}=\frac{19}{7} *x$

Now to remove 9/7 we take reciprocal and multiply it on both sides

$\frac{19}{5} * \frac{7}{19} =\frac{19}{7}* \frac{7}{19} *x$

$\frac{7}{5}=x$

The missing number is $\frac{7}{5}$

Answer 2

Answer is 10 11/35 

Because here you are finding an unknown, so you redo the problem.
The problem tells you to divide so the opposite is times the number
so 2 5/7 times 3 4/5 is 10 11/35
