A "quick picture" is an estimate than?

5 x 2.7 ..... 5 x 3= 15

Its been a long time since elementary school and I do not remember "quick picture"

The question was How can you use a "quick picture" to find 5 x 2.7?
the answer is 13.5.......an estimate would be 15

Right. The estimate is 14 since 2.7 is a little less than 3. However, 15 may be an acceptable estimate.

A "quick picture" refers to a visual representation or mental image that helps you estimate a mathematical calculation, such as multiplication. It is a method often used in elementary school to provide a rough estimate of the result.

To use a "quick picture" to find the product of 5 x 2.7, you can imagine the visual representation of the calculation. In this case, you can picture 5 groups of 2.7.

Start by visualizing 5 groups or sets of 2.7. Since 5 is a whole number, you can represent it as 5 complete sets or objects. Then, multiply each set or object by 2.7.

In the case of multiplication, you can simplify the calculation by using smaller whole numbers. For example, you can round 2.7 up to 3, which is a whole number.

Using this simplified "quick picture," you can imagine 5 groups of 3. When you multiply 5 by 3, you get 15. Therefore, as you mentioned, the result of 5 x 2.7 using a "quick picture" is approximately 15.

However, it's important to note that the precise result of 5 x 2.7 is 13.5. The "quick picture" method is a way to estimate the result but may not provide the accurate answer.
