Barbara is tiling her craft room floor with square tiles. she wants 6/10 of the square tiles to be red. if she uses 18 red, how many square tiles will be used to cover the floor?

18 is 6/10

18/1 = 6/10

Cross multiply

18x10 is 180

180/6 is 30 tiles total

Step-by-step explanation:

30 square tiles will be used to cover the floor.

Step-by-step explanation:

To find the number of tiles that will be used to cover the floor, we will have to interpret the statement mathematically and then solve.

Let x be the total number of tiles that will be used to cover the floor.

From the statement above, Barbara uses 6/10 of the square tiles which is  18 red.

so, 6/10 of the square tiles is equal to 18 red

which implies;

   of  x   =  18

× x  =  18

  =    18

cross multiply

6 × x  =  18  ×  10

6x  = 180

Divide both-side of the equation by 6

  =  

(At the left-hand side of the equation, the 6 on the numerator will cancel-out the 6 at the denominator leaving us with just x while at the right-hand side of the equation 180 will be divided by 6)

x   =

x = 30

Therefore, the number of square tiles that will be used to cover the floor is 30.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
