Answer:
If two powers have the same base then we can multiply the powers. When we multiply two powers we add their exponents.
Step-by-step explanation:
is an expression. And an expression is like an equation except that it has no "sides". Expression is something after being solved gives the answer. An equation on the other hand, shows something being equal to something else.
Since the word, 'of' means to multiply, whenever we see of multply the two numbers.
Then there are two ways to dothis, sicne to convert a percentage into a decimal, you devide by 100, we can either do this after we multiply or bfore, it doesn't matter so I'm going to do it after.
1. 520x100=52000/100=520
2. 20.25x3=60.75/100=.6075
3. .15x250=37.5/100=.375
4. 200x79=15800/100=158
5..3x80=24/100=.24
6. .28x50=14/100=.14
