Answer to Problem 7A

  1.597

Explanation of Solution

Given information:

An expression is given as 0.69÷0.432

Calculation:

We have been given an expression as 0.69÷0.432.

Rewriting the given expression 0.690.432=0.690.432×10001000=690432

Dividing given two numbers,

  2.56

Explanation of Solution

Given information:

An expression is given as 0.92÷0.36

Calculation:

We have been given an expression as 0.92÷0.36.

Rewriting the given expression 0.920.36=0.920.36×100100=9236

Dividing given two numbers,

  362.555 92 72 200 180 200 180 20
