Question

Plaese help !!!
5/7m=15

Answer 1

Here is the equation:

`(5)/(7) m = 15 \rightarrow (5)/(7) * m = 15`

In this question, you are going to be multiplying. Switch it around. Remember that the sign changes!

`(5)/(7)* m = 15 \rightarrow 15 / (5)/(7) = m`

Divide to find m. When dividing, you have to multiply. You use: Keep, Change, Flip.

Keep 15, Change ÷ to ×, Flip 5/7 = 7/5. Your new equation is:

`15 / (5)/(7) = (15)/(1) * (7)/(5)`

Now multiply:

`(15)/(1) * (7)/(5) = (105)/(5) = 21`

m is equal to 21; m = 21

Answer 2

`(5)/(7)m = 15`

Multiply both sides by 7/5.

`(7)/(5) * (5)/(7)m = (7)/(5) * 15`

`(35)/(35) m = (7 * 15)/(5)`

`(35)/(35) m = (7 * 3 * 5)/(5)`

`m = (7 * 3)/(1)`

`m = 21`
