$24.96^2 \div (34.11 \div 20.05) + 67.96 - 89.11 = x$

$200 \div 25 \times 4 + 12 - 3 = x$

Evaluate: $(923 - 347) / x = 32$

Solve $1\frac{4}{5} + 20 - 280 \div 25 = x$

Directions: What approximate value should come in place of question mark($x$) in the following questions? (NOTE: You are not expected to calculate the exact value). $421 \div 35 \times 299.97 \div 25.05 = x^2$

Directions: What approximate value should come in place of question mark($x$) in the following questions? (NOTE: You are not expected to calculate the exact value). $19.99 \times 15.98 + 224.98 + 125.02 = x$

Evaluate : $123 \times 999 + 123$
