3. 1/2

6. 56

8. 500

Step-by-step explanation:

3. There are 9 white socks. All other socks are non-white socks. 8 + 3 + 7 = 18    

This means that there are 9 white socks to 18 non - white socks or 9:18 or 9/18. BUT, you can reduce it. You can say for every 1 white sock, there is 2 non-white socks. So, it is 1:2 or 1 to 2 or 1/2. They only listed fractions which means it is 1/2.

6. So, I think its easier to put it into a fraction like this:

          7                                     ?

          8                                    64

This means there is 7 men for every 8 female people. How did 8 go to 64? x8. What you have to do with the denominator you have to do with the numerator. 7 x 8 = 56

          7                                    56

                   =                      

          8                                    64

So, the answer is 56.

8.  Let's put it into a fraction again:

         20                                   40

        250                                   ?

This means for every 20 feet you need 250 bricks. How did 20 go to 40? x2. What you have to do with the denominator you have to do with the numerator. 250 X 2 = 500

         20                                  40

                      =                  

        250                               500

So, the answer is 500.

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
