Why this matters

60% off. EMI at 12% per annum. Cricket strike rate 145.7. Ratios are how we compress a fact into a single number and compare across totally different scales.

Percentages decide your marks, your discounts, your loans, your tax slab, and every metric on your Instagram profile. There is no adult life without ratios.
