Population is a component of the total ______________

Approximate the value of (19.98 × 5.02) ÷ 0.99

49.99% of 5400 + 923=?

499.98% of (√440.8 + 12.92² ) - 12.02 of 4.82 = ? of 9.82 + 9.98% of 999.94

59.68% of √400 × 123.95 = ?

11.06 ² – 7.12 × 4.88 + 9.96 = 12.22 × ? 

Find the ratio of the area of an equilateral triangle of side ‘a’ cm to the area of a square having each side equal to ‘a’ cm.

30.05% of 149.97 + ? X 8.88 = (39.95 + 12.01² - 13.032²)² 

26.23 × 31.82 + 44.8% of 1200 + ? = 1520

(2744)^1/3 × 10.11 × 5.97 ÷ 14.32 = ? + 15.022
