6/16 OR 30/80 WHICH ONE is bigger?

2 answers:

8 0

There's two possible ways to find the answer to this. First you can find a common denominator to reduce both to. In this case, they can both reduce to a common denominator of 8. So 6/16 reduces to 3/8 and 30/80 also reduces to 3/8, so they are equal. The other way is to use a calculator and turn them into decimals by dividing the numerator by the denominator. They both come out to be .375. Once again they are equal. You can use whichever method is easier for you.

You have to change them to the same denominator (bottom). The quickest way to do this is to x them by each other.. 16 x 80 = 1280
Then x the top of each by what you x'd the bottom by to get the common denominator...
6 x 80 = 480
30 x 16 = 480
The fractions would now be 480/1280 and 480/1280. They are the same. 6/16 is an equivalent fraction to 30/80. Neither is bigger.
Hope this helps :)

What is the value of the expression?

Blababa [14]

Answer:

- $\frac{9}{10}$

Step-by-step explanation:

Step 1: Add the numerator fractions.

2/5 + 3/10

Here we have to find LCD, the LCD of 5 and 10 is 10

(2*2) + 3 4 + 3

Therefore, 2/5 + 3/10 = --------------- = ------------------

10 10

= 7/10

Step 2: Now substitute 2/5 + 3/10 = 7/10 in the given fraction, we get

7/10

= ----------

-7/9

If we have fraction over fraction, we have to find the reciprocal of denominator fraction and multiply.

The reciprocal of -7/9 is -9/7

Step 3: Now multiply 13/10 and -9/7

= (7/10) x (-9/7)

= -9/10

=-9/10

The answer is - $\frac{9}{10}$

Answer:

Measure of the unknown angle is 21°.

Step-by-step explanation:

In the given question,

Measure of opposite side and the measure of hypotenuse have been given.

Therefore, we will use the trigonometric ratio for the unknown angle which has the ratio of opposite side and the hypotenuse.

$\text{sin}\theta=\frac{\text{Opposite side}}{\text{Hypotenuse}}$

$=\frac{13}{36}$

$=0.36111$

$\theta \approx \text{sin}^{-1}(0.36111)$

$\theta \approx 21.17$

$\theta \approx 21^{\circ}$

Therefore, measure of the unknown angle is 21°.

stellarik [79]

Answer:

146 people

Step-by-step explanation:

The formula for mean = sum of values/number of values

For Monday to Friday , the average number of people that came = 98

Hence, the total number of people that came is calculated as:

Number of people that attended Monday to Friday = 98 × 5 = 490 people

The number of people that came on Saturday = 162 people

The mean average for the whole week is 114.

The number of days in a week = 7 days

The number of people that came in on Sunday is represented = x

Therefore,

490 + 162 + x/7 = 114

Cross Multiply

652 + x = 798

x = 798 - 652

x = 146 people

Therefore, 146 people visited on Sunday
