Q.Express the time by using decimal?
Can you send me a video?

Dear student,

you can express time in decimals as
 
i am giving some examples here 
30 mins is half an hour so you can write 30 minutes in decimal as 0.5
25 mins is quarter  hour so you can write 25 minutes in decimal as 0.25
​​​​​​45 mins is 3-quarter hour so you can write 45 minutes in decimal as 0.75
so to convert minutes in decimal you have to divide by 60 and then convert in decimal . 

40minutes =  40/60 = 4/6 =  0.66

so,if you want to write in 7:30 am in decimal it will be 7.5 decimal hours.

9:25 am in decimal it will be 9.25 decimal hours.

ẃe can not provide you video here yôu can refer to video lessons provided in your course
