Find the smallest number which when divided by 7, 9 and

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.

(5/9 of 2699.81) + (49.88% of 144.18) - (2/7 of 489.77) = ?

59.978% of 800.315 - 229.95 = ? - 24.95% of 200.15

(32.18% of 2399.89 - √624 × 26.25) % of 149.79 = ?

What approximate value will replace the question mark (?) in the following?

960.02 of 238.89 ÷ 144.01 of 79.97 = ?

 (1782 ÷ 11.98) ÷ 2.92 × 35.89 + 25% of 541 – 67% of 1299 = ?

99.99% of 9.99 + 299.98% of 129.98 = ?²
