anastassius [24]

Answer:

2/6 is NOT equivalent to 20%

Step-by-step explanation:

2/6 is NOT equivalent to 20%

Reason :

To convert 2/6 to percentage

Multiply 2/6 by 100

That is ,

= 2/6 × 100 %

= 1/3 × 100 %

= 100/3 %

= 33.33%

33.33% is not same as 20%. Therefore 2/6 is not equivalent to 20%

Johnny played 31/2 video games in an hour.How many could be play in 40 minutes ?

REY [17]

<u>Answer: </u>

Johnny could play $2\frac{1}{3}$ video games in 40 minutes.

<u>Explanation:</u>

Given:

Johnny played video games in an hour = $3\frac{1}{2}$

To Find:

Video games Jonny can play in 40 minutes =?

Solution:

number of videos games Jonny can play in 1 hour = $3 \frac{1}{2}$ = $\frac{7}{2}$

And as 1 hour = 60 minutes ,

So number of videos games Jonny can play in 60 minutes = $\frac{7}{2}$

=> Videos games Jonny can play in 1 minute = ${\frac{\frac{7}{2}}{60}$

=> $\frac{7}{20\times 6}$

=> $\frac{7}{120}$

=> Videos games Jonny can play in 40 minute = 40 x Videos games Jonny can play in 1 minute

=> Videos games Jonny can play in 40 minute = $40 \times \frac{7}{120}$

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

Hence Johnny could play $2\frac{1}{3}$ video games in 40 minutes.
