128 is 74% of what number?
Hatshy [7]
74% means 0.74
"of" means "times"

So,    128 = 0.74 times (the number)

Divide each side of this equation by 0.74 :

128/0.74 = the number

<em>172.973</em> (rounded) = the number

Belle is going to make chili for a football party. It will take 1 hour and 10 minutes to prepare all the ingredients and assembl
MrRa [10]

Answer:

1:10pm

Step-by-step explanation:

1st, you add all the time needed to make the chili & cook it.

1 hour + 10 minutes + 1 hour + 40 minutes =  2 hours & 50 minutes.

Now you work backwards from 4:00pm.

You go back 2 hours & you would be at 2:00pm

Now you go back another 50 minutes & you would be at 1:10pm

To double check, you can add 2 hours & 50 minutes to 1:10pm & you would get 4:00pm
