Question

Use the fractions to write and evaluate a multiplication expression that represents 70% of 400. Compare the answer to the one you got using the model.

Answer 1

70% can be written as 70/100. So, a multiplication expression showing 70% of 400 can be written as:

400 * (70/100)
400 * 70 = 28,000
28,000/100 = 280

Answer 2

`70\% \text{ of } 400=280`

Explanation:

To find : Use the fractions to write and evaluate a multiplication expression that represents 70% of 400.

Solution :

Expression 70% of 400 is written as,

`70\% \text{ of } 400=(70)/(100)* 400`

`70\% \text{ of } 400=70* 4`

`70\% \text{ of } 400=280`

Therefore,
`70\% \text{ of } 400=280`
