Answer 1

we have the expression

4÷5×6+7×55

Remember that

Applying PEMDAS

P ----> Parentheses first

E -----> Exponents (Powers and Square Roots, etc.)

MD ----> Multiplication and Division (left-to-right)

AS ----> Addition and Subtraction (left-to-right)

so

step 1

Multiplication and Division (left-to-right)

5x6=30

7x55=385

substitute in the given expression

4÷30+385

step 2

Multiplication and Division (left-to-right)

4÷30=0.13

substitute

0.13+385

step 3

Addition and Subtraction (left-to-right)

0.13+385=385.13

therefore

the answer is 385.13
