Answer:
2.25 divided by 0.6 : Yes and 5.2 divided by 8, 3.63 divided by 3, 71.1 divided by 9 : No
Step-by-step explanation:
We have that when two numbers are divided, they can be written in the form , where p is the dividend and q is the divisor.
Now, when we divide 5.2 by 8, we can write
Also, the division 3.63 by 3, can be written as = 1.21
Further, when we divide 71.1 by 3, we can write = 23.7
We can see that above divisions are easy divisions and do not require to write any type of 0 in the numerator.
Moreover, when we divide 2.25 by 0.6, we can write =
.
So, we get that in the last division, we need to write a zero in order to multiply the numerator with 10 for easy division.
Hence, 2.25 divided by 0.6 : Yes and 5.2 divided by 8, 3.63 divided by 3, 71.1 divided by 9 : No
To answer this question you will set up the proportion shown in the attached picture.
There are 2 ways to solve this.
1. You can create an equivalent ratio by determining the factor that will take you from 1 cm to 2 cm and apply his factor to the 19 miles.
The answer would be 19 x 2= 38 miles for 2 centimeters.
2. The second strategy is to use cross products to get an answer. You multiply the number diagonal from each other. See picture for this work.
