Answer:

78.787878787879

Step-by-step explanation:

Solution:

Since

60 : 99 = X : 130

Then we know

60/99 = X/130

Multiplying both sides by 130 cancels on the right

130 × (60/99) = (X/130) × 130

130 × (60/99) = X

Then solving for X

X = 130 × (60/99)

X = 78.787878787879

Therefore

60 : 99 = 78.787878787879 : 130
