In which number is the digit 5 one-tenth as much than it is in the number 25,973?
garik1379 [7]

Let's first look at the number that we are given.25,973. We would read this number as eighty-nine and five hundred forty seven thousandths.

In this number, the 5 is in the tenths place. That is equivalent to 5/10 or five tenths (five divided by ten or 0.5).

The questions asks you to write a number in which the digit "5" is one-tenth the value of the number 5 in 25,973

You are looking for a number that is one-tenth of 0.5. Remember, one-tenth equals 1/10 which equals 0.1.

One-tenth of 0.5 equals 0.1 multiplied by 0.5 which equals 0.05. Hence, the number 5 has to be in the hundredths place to answer the question.

Using the number that we were given (89.547), if you multiply 25,973 by (1/10) you get 8.9547.

In the number 8.9547, the digit 5 is one-tenth the value of the number 5 in 25,973

The answer is 8.9547.

I hope this explanation helps.

How do graphs and equations reveal information about a relationship between two quantities
fiasKO [112]
Graph and equation both shows the proportional comparison between two quantities

for example, equation y = 4x, this means, the value of 'y' will always be 4 times the value of 'x'

More complex equation such as y = 3x + 5, means that the value of 'y' equals to 5 more triples of value of 'x'

Another example is the conversion graph attached below, it shows the relationship between kilometers and miles. For example, we want to find out how many miles are in 10 kilometers, we would draw a line from the point that shows 10 km towards the graph, then across from the graph to miles, and we'd get a reading of 12 miles.
