Can you workout this problem
Vinil7 [7]
Hi,

Work:

Equation;

35 - 3 \times  {10}^{2}  \div 20
1. Write division as fraction.

35 -  \frac{3 \times  {10}^{2} }{20}

2. Evaluate the power of 10².

35 -  \frac{3 \times 100}{20}

3. Reduce the fraction with 20.

35 -  \frac{3 \times   100}{20}  = 35 - 3 \times 5

4. Multiply.

35 - 15

5. Finally subtract and RESULT.

35 - 15 = 20


Hope this helps.
