`(601/49)xx(399/81)` ÷ `(29/201)` = ?

30.05% of 250.05 – 15.15% of 99.99 × 2.02 = ?

12.5% of 6400 + (17 × 25) = ?% of 2200+ 125 

(? + 6.06^3.03 ) ÷ 10.08 + 21.89 × 6.97 = 1979.97 ÷ 10.96

In a cyclic quadrilateral ABCD, angle A = 70 degrees and angle B = 100 degrees. What is the measure of angle C?

? = 650.24 + 1124.97 – 14.99²  

? ^2.03 + 121.96 – 55.98 + 129.78% of 59.98 = 399.98

185.92 ÷ 5.98 - (4.002 ² + 114.03 of 5.03 ÷ 18.99 of 6.04 = 5.01 of 2.99 + ? ÷ 12.02

√49 + 6.66% of 1725 + 22² = ?² - √361 

(71.78 × 59.88 ÷ 17.92 ÷ 120.22 × 161.72)% of 32 = ?
