[tex] \dfrac{5}{7}m = 15 [/tex]

Multiply both sides by 7/5.

[tex] \dfrac{7}{5} \times \dfrac{5}{7}m = \dfrac{7}{5} \times 15 [/tex]

[tex] \dfrac{35}{35} m = \dfrac{7 \times 15}{5} [/tex]

[tex] \dfrac{35}{35} m = \dfrac{7 \times 3 \times 5}{5} [/tex]

[tex] m = \dfrac{7 \times 3}{1} [/tex]

[tex] m = 21 [/tex]

Here is the equation:

[tex] \frac{5}{7} m = 15 \rightarrow \frac{5}{7} \times m = 15 [/tex]

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

[tex] \frac{5}{7}\times m = 15 \rightarrow 15 \div \frac{5}{7} = m [/tex]

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:

[tex] 15 \div \frac{5}{7} = \frac{15}{1} \times \frac{7}{5} [/tex]

Now multiply:

[tex] \frac{15}{1} \times \frac{7}{5} = \frac{105}{5} = 21 [/tex]

m is equal to 21; m = 21
