6 0

Answer:

20%.

Step-by-step explanation:

That is (60 - 50) / 50

= 10/50

= 1/5

To convert to a percent we multiply by 100:

= 20%.

6 0

I think it will be 10% because you invited 50 right? And 60 atended or was it 60 and 50 atended? Well either way I think it’s 10%

Three friends recorded, in different units, the lengths of the hopscotch paths they made.

ivann1987 [24]

From the options given, Dustin's hopscotch path was the longest in comparison to the other two friends.

<h3>How to find out who had the longest path?</h3>

Make sure all distances use the same units.
If necessary convert the distances.
Compare the distances.

Based on this, let's make sure all distances are in feet.

Cassey: 94 feet

Jasmin: 1100 in or 91.66 feet
Each inch is equivalent to 0.0833

1100 x 0.0833 = 91.66

Dustin: 32 yards or 96 feet
1 yard = 3 feet
32 x 2 = 96 feet

Based on this, the person with the longest path is Dustin.

I am an improper fraction whose numerator and denominator are made of odd digits only. In my simplest form, my representation as

ASHA 777 [7]

Answer:

The fraction is = $\frac{21}{9}$

Step-by-step explanation:

In simplest form the fraction is represented in mixed number as $2\frac{1}{3}$ .

The fraction form of the mixed number can be given as :

$2\frac{1}{3}=\frac{7}{3}$

Let the fraction be = $\frac{7x}{3x}$ [As multiplying same numbers to numerator and denominator does not affect the proportion.

Sum of numerator and denominator is = 30

This, can be represented as:

$7x+3x=30$

Solving for $x$ .

$10x=30$

Dividing both sides by 10.

$\frac{10x}{10}=\frac{30}{10}$

$x=3$

So, the fraction will be = $\frac{7\times 3}{3\times 3}$

⇒ $\frac{21}{9}$
