48 * 5 = 240
240 / 32 = 7.5 gallons a week ( $28.42)
Solution:
As, we have to find , % of 20
If we have to Percent of a certain number it means , divide that number by 100 , for example x% means .
And if i am writing , x% of y it means , .
When you have to find the part of a number, remember that you have to multiply the two numbers (fraction and whole number)
In a day there are 24 hours.
3/8 of a day
Process:
24 X 3/8 = 9
We sleep 9 hours of the day.
Bascially you go 3/8 = .375 Then multiply .375 x 24 = 9
To answer the problems correctly, you have to follow and pay close attention to whether or not it says "Area" or "Perimeter". For example, for the first problem, area of 63 square units, you would have to create a shape thats sides multiply out to equal 63 units squared. He could draw a square with 9 units by 7 units. This would work because 9x7=63. For perimeter, all four sides must add up to equal 38 units. Feel free to get creative with the shape on this one! If you have any other questions, just ask. Hope I helped some. :)
