Answers

Answer 1

Answer:

The correct answer is B. If Alina’s workout was 80 minutes, and Dane’s workout was 48 minutes, they spent the same amount of time on cardio exercise.

To figure this out, first find 15% of 80 and then 25% of 48.

To find 15% of 80, you can first find 10% of 80 which is 8(just move the decimal one place to the left). The remaining 5% will be half of 8 since 8 is 10%. Add both the numbers up and you will get 12. (8+4=12)

To find 25% of 48, you can divide 48 by 4. Since percent means 'out of 100', 25% is 25 of 100. 100 divided by 25 is equal to 4. So, 48 divided by 4 is equal to 12.

So, the final answer is B. They both equal to 12.

Let me help you out!

A unit rate is something per one.

That means that we also need to include units so that we could know what we are talking about.

Basically divide, since this one is simple.

183/3 = 61

Describe a situation where it is easier to use decimals than fractions , explain why .

Answers

Answer:

Handling Money

Step-by-step explanation:

Fractions are of the form $(a)/(b)$ , where a and b are integers with b≠0. They, represents some part of the whole number.

Decimals are those fractions in which the denominators are powers of ten and numerators are the figures placed to the around the decimal point.

For e.g. 7.8 = $(78)/(10)$

Now, there are many situations where using decimals are effective than using fractions.

For e.g. While handling money, decimals prove fruitful than fractions.

That is $2.45 is much easier to work with than $ $(245)/(100)$ i.e. $ $(49)/(20)$ .

When you must multiply non whole numbers, decimals are easier to manipulate in the sense that setting up a multiplication problem with decimals rather than fractions is much simpler and easier to calculate.
