Solve for r. (enter answer as a fraction)

⁴⁄_r = ⁵⁄₇

r =

Stuck? or

Hint
1
of
5

Multiply both sides by r.

r X ⁴⁄_r = ⁵⁄₇ X r

Hint
2
of
5

4 =⁵⁄₇r

Hint
3
of
5

Multiply both sides by ⁷⁄₅.

4 X ⁷⁄₅ = ⁵⁄₇ r X⁷⁄₅

Hint
4
of
5

^4 X 7⁄₅ = r

Hint

5

r = ²⁸⁄₅

Solve for r. (enter answer as a fraction)

⁴⁄_r = ³⁄₁₀

r =

Stuck? or

Hint
1
of
5

Multiply both sides by r.

r X ⁴⁄_r = ³⁄₁₀ X r

Hint
2
of
5

4 =³⁄₁₀r

Hint
3
of
5

Multiply both sides by ¹⁰⁄₃.

4 X ¹⁰⁄₃ = ³⁄₁₀ r X¹⁰⁄₃

Hint
4
of
5

^4 X 10⁄₃ = r

Hint
5
of
5

r = ⁴⁰⁄₃

Solve for r. (enter answer as a fraction)

⁴⁄_r = ⁵⁄₉

r =

Stuck? or

Hint
1
of
5

Multiply both sides by r.

r X ⁴⁄_r = ⁵⁄₉ X r

Hint
2
of
5

4 =⁵⁄₉r

Hint
3
of
5

Multiply both sides by ⁹⁄₅.

4 X ⁹⁄₅ = ⁵⁄₉ r X⁹⁄₅

Hint
4
of
5

^4 X 9⁄₅ = r

Hint
5
of
